I’m glad my sister slept with my boyfriend.

The Unraveling and the Sabotage

I knew my sister better than anyone. I knew exactly what she was like when she didn’t get what she wanted. Christy not getting something she never knew existed was one thing. Christy finding out she had it and gave it away, that was going to be nuclear.

The only question was how long until she found out. Honestly, it didn’t take long at all. Mason called his mom a week later to tell her the mortgage was paid off. I was sitting next to him on his couch when he made the call. I watched his whole face light up as she cried happy tears on the other end. It was one of the most genuine moments I’d ever witnessed.

What neither of us realized was that Christy had shown up unannounced again, still using the key she refused to give back. She was standing in the hallway when she heard him say, “It’s done, Mom. The whole thing. You and Dad never have to worry about the house again.”

Then we heard someone screaming like a banshee. It was Christy.

“How?” Christy shrieked, storming into the living room like a tornado in designer heels. “How did you pay off a mortgage, Mason? That’s hundreds of thousands of dollars. Where did you get that kind of money?”

Mason’s face went pale. He ended the call with his mom and stood up slowly.

“Christy, you need to leave.”

“I’m not going anywhere until you tell me what the hell is going on,” she screamed. Her eyes were wild, darting between me and Mason like she was trying to solve a puzzle that would ruin her life. “You work a normal job. You drive a 10-year-old car. You told me you couldn’t afford to take me to Cabo for my birthday. And now you’re paying off mortgages.”

“It’s none of your business,” Mason said. His voice was calm, but I could see his hands shaking slightly. “We’re not together anymore. Remember? You made sure of that.”

Christiey’s head snapped toward me. “You?” she hissed. “You knew. You knew this whole time, didn’t you? That’s why you agreed to sign that contract so easily. You knew he had money and you played me.”

“Are you hearing yourself right now?” I scoffed. “You proposed the swap. You wrote the contract. You forced everyone to sign. I didn’t even want to be part of this ridiculous situation, but you and Leon made that choice for me.”

“There’s no way this is a coincidence,” Christy insisted. Her voice was getting higher and more unhinged with every word. “You must have found out somehow. Maybe you went through his stuff. Maybe you hacked his bank account. I don’t know how, but you knew and you stole him from me.”

“I didn’t steal anyone,” I shot back. “You threw him away. You literally handed him to me on a silver platter because you wanted my neglectful checked out boyfriend instead. That was your choice, Christy. No one made you do that.”

“I didn’t have all the information,” she screamed.

“If I had known he was rich, you would have pretended to love him,” I finished. “That’s exactly why he didn’t tell you. He knew you’d only want him for his money. And look at you right now, proving him right.”

Christiey’s face turned a shade of red I’d never seen before. She looked like she was about to spontaneously combust.

“This isn’t fair,” she wailed. “I deserve to know these things. We were together for a year. You should have told me.”

“Why?” Mason asked quietly. “So you could suddenly find me interesting? So you could pretend the staying home and cooking and comfortable life wasn’t boring anymore? I know exactly how that conversation would have gone, Christy. You would have loved everything about me the second you found out there was money attached. And that’s exactly why I never told you.”

Christy opened her mouth to respond, but nothing came out. For once in her life, she had nothing to say. She grabbed her purse and stormed out, slamming the door so hard a picture frame fell off the wall.

I thought that would be the end of it. I was wrong. The next morning, my phone exploded with calls from my mother. When I finally answered, she told me Christy had called an emergency family meeting. I needed to come home right now, no excuses.

I walked into my parents living room an hour later to find Christy already in position. She was curled up on the couch with a blanket around her shoulders. Tissues were scattered around her, eyes red and puffy from what I assumed was strategically timed crying. My mom sat next to her rubbing her back. My dad stood by the fireplace looking uncomfortable.

“Bailey,” my mom said in that soft, disappointed voice she reserved for moments when she thought I’d done something wrong. “We need to talk about this situation with Mason.”

“Let me guess,” I said flatly. “Christy told you her version and now I’m the bad guy.”

“No one said that,” my mom said. “Your sister is hurting.”

Christy let out a theatrical sob. “I just want things to go back to normal,” she whimpered. “I made a mistake. I admit it. I should never have suggested the swap. But Bailey is rubbing it in my face and refusing to switch back and it’s not fair.”

“A mistake?” I repeated. “You planned this for weeks. You drafted an actual contract. You brought a pen to dinner, Christy.”

“I didn’t know what I was giving up,” Christy wailed. “He kept things from me. He hid who he really was. How was I supposed to make a fair decision without all the information?”

“So now it’s his fault you treated him like garbage?” I asked. “He didn’t owe you his bank statements. You were supposed to love him, not treat him like a wallet.”

My dad cleared his throat. “Bailey, maybe your sister has a point. This whole thing has gotten out of hand. Why don’t you just end it early and let everyone move on? She hasn’t stopped crying.”

“She’s crying because she missed out on millions,” I said. “Not because she lost some great love. If Mason was still broke, she’d be at brunch right now posting selfies with Leon.”

“That’s not fair,” Christy insisted. “You don’t know what’s in my heart. I had something real with Mason and I didn’t see it.”

“Is that what you want me to say? Fine. I was blind. I took him for granted, but I see it now.”

“You see his wallet?” I said. “That’s not the same thing.”

My mom sighed. “Bailey, please just consider ending this early. For the family’s sake.”

I looked at my parents, at my sister, at the perfectly orchestrated intervention designed to guilt me into giving Christy what she wanted. I felt something cold and final settle in my chest.

“No,” I said. “The contract says one month minimum. No backing out early. No running to mom and dad.” I looked directly at Christy. “Those were your rules. You wrote them specifically so I couldn’t escape when things got hard. Well, guess what? Now you can’t escape either. You want to be with Leon so badly? Go be with him. Leave me and Mason alone.”

I walked out before anyone could respond.

Two days later, Mason showed up at my apartment looking exhausted. He dropped onto my couch and pulled out his phone without saying a word.

“You need to see this,” he said, handing it to me.

I scrolled through the messages from Christy. There were dozens of them, maybe hundreds.

“I made the biggest mistake of my life. Please give me another chance. I miss you so much. I miss your cooking. I miss your hugs. I miss everything about you. I’ll change. I promise. I’ll stay home every night. I’ll watch whatever you want. I’ll never complain again. I love you, Mason.

I’ve always loved you. I was just too stupid to see it. I’ll cook for you. I’ll learn all your favorite recipes. I’ll be the girlfriend you always deserved. Please, I’m begging you. I’ll do anything. Anything.”

I looked up at Mason. “She’s offering to cook. That’s how you know she’s desperate.”

“She once told me she’d rather die than learn how to use a stove,” he said flatly. “Now she’s offering to make me breakfast, lunch, and dinner.”

“She’s also offered to delete Instagram, stop going to clubs, and quote, ‘Be happy with a boring life as long as it’s with you,’ ” I read.

“Wow,” I said. “She really wants that money.”

He took his phone back and tossed it on the coffee table.

“I’m not responding. I’m done.”

“What are you going to do?”

He looked at me and something in his expression made my chest tighten.

“Stay right here,” he said.

She begged. She cried. She dragged our parents into it. She blew up his phone with messages saying things she never said once during their entire relationship. Nothing worked. The contract she created to trap me was now the thing keeping her locked out.

But if you think my sister just gave up after that, you don’t know her at all. When begging doesn’t work, she switches tactics. What she did next almost destroyed everything I was building with Mason.

The next two weeks with Mason were the happiest I’d been in years. We fell into a rhythm that felt natural in a way my relationship with Leon never had. Mason cooked dinner while I sat on his kitchen counter, and we talked about everything and nothing.

He remembered that I liked my eggs over medium, and that I hated cilantro. He remembered that I always needed a glass of water on my nightstand before bed. These were small things, things Leon never bothered to learn in 2 years.

One night, we stayed up until 3:00 a.m. watching terrible horror movies and making fun of the bad acting. Another night, he taught me how to make his grandmother’s pasta recipe. He didn’t get frustrated when I overcooked the noodles twice.

He laughed and said, “Third times the charm.” And it was.

We ate that pasta on his living room floor because neither of us wanted to move to the table. It was the best meal I’d ever had.

“You know what I like about you?” Mason said one night while we were lying on his couch. My head was on his shoulder, some cooking show playing in the background that neither of us were watching.

“My devastating wit and charm,” I offered.

He smiled. “You don’t perform. You just exist. You’re not trying to be anything other than exactly who you are. Being with you feels like I can finally breathe.”

My chest tightened in the best way. “I don’t think anyone’s ever said that to me before.”

“Then no one’s been paying attention,” he said quietly. He shifted so he could look at me properly. “I mean it, Bailey. You’re funny and sharp and you don’t pretend to be someone you’re not. That’s rare. That matters.”

I didn’t know what to say. I wasn’t used to someone seeing me like that. I wasn’t used to being enough exactly as I was.

“You matter, too,” I finally said. “Just so you know, you’re not boring or safe or whatever other stupid words people have used. You’re steady. You’re kind. You remember things. You show up. That’s everything.”

Mason’s expression softened in a way that made my heart stutter. I kissed him for the first time that night. It felt like the most natural thing in the world.

Christy must have sensed that something had changed because that’s when the sabotage started. Our first real date was at a small Portuguese restaurant Mason loved. We were halfway through our appetizers when I heard a familiar voice behind me.

“Oh my god, what a coincidence,” Christy said, appearing at our table like she’d materialized from thin air. She was dressed to kill, full makeup, heels that could double as weapons.

“I didn’t know you two would be here. Mind if I join?”

“Yes,” I said flatly. “We mind.”

She ignored me and pulled up a chair anyway, positioning herself right between us.

“So, how’s it going?” she asked, eyes fixed on Mason. “Getting to know each other, taking things slow, I hope. You really shouldn’t rush into anything serious. Rebound relationships never work out.”

“This isn’t a rebound,” Mason said. His voice was calm, but I could see his jaw tightening. “And you weren’t invited, Christy.”

“I’m just looking out for both of you,” she said sweetly. “Bailey doesn’t have the best track record with relationships, and I don’t want you to get hurt, Mason. You deserve someone who’s going to stick around.”

“Like you stuck around?” I asked. “When you traded him for someone more exciting?”

Christiey’s smile flickered but didn’t drop. “I made a mistake. I’ve admitted that. But Bailey rushing into something with you isn’t going to fix anything. She’s just using you to get back at me.”

Mason stood up and dropped cash on the table.

“We’re leaving,” he said, reaching for my hand. “Don’t follow us.”

We walked out and left Christy sitting alone at the table. But that wasn’t the end of it. She showed up at the next date, too, and the one after that. It happened at a coffee shop, a movie theater, a bookstore where Mason wanted to show me his favorite section.

Every single time she appeared out of nowhere with some excuse about coincidence or concern. Every single time she found a way to mention that I was moving too fast. She claimed Mason deserved better or that rebound relationships were doomed to fail.

When the direct sabotage didn’t work, she switched to a different approach. Suddenly, every family member I had was texting me with concerns. My aunt wanted to know if it was true that I’d manipulated Christy into the swap. My cousin asked why I was being so cruel to my sister during her time of need.

My mom called three times in one week to tell me that Christy was barely eating and couldn’t stop crying. She asked if I felt any guilt at all.

“She’s telling everyone I planned this,” I told Mason one night, scrolling through yet another concerned text from a relative I barely talked to. “She’s saying I knew about the money and I tricked her into the swap so I could steal you.”

“That’s insane,” Mason said. “You didn’t even want to sign the contract.”

“She’s rewriting history,” I said. “And everyone’s believing her because she’s Christy. She’s the pretty one, the charming one, the one who always gets what she wants. And I’m just Bailey, the difficult one who ruins everything.”

Mason took my phone out of my hands and set it face down on the table.

“You’re not the difficult one,” he said firmly. “You’re the only one in your family who sees her clearly. That doesn’t make you difficult. It makes you honest.”

Christy called me that night. I don’t know why I answered. Maybe I was hoping she’d finally say something real, something that wasn’t manipulation or guilt or strategy.

“You’re really doing this,” she said. Her voice was cold, controlled. “No more theatrical crying. You’re really choosing a man over your own sister.”

“I’m not choosing anyone over you,” I said. “You did this, Christy. All of it, the swap, the contract, everything that’s happening right now is because of choices you made.”

“He was mine,” she hissed. “For a whole year, he was mine and you just swooped in and took him the second you saw an opportunity.”

“You threw him away,” I said for the hundredth time. “You literally handed him to me and told me to sign a contract saying I’d keep him for a month. Now you’re mad that I actually like him. That’s not my fault, Christy. That’s yours.”

She was quiet for a long moment. When she spoke again, her voice was barely above a whisper.

“You’re going to regret this,” she said. “I’m your sister, Bailey. Blood, and you’re throwing that away for some guy you’ve known for mere weeks.”

“I’m not throwing anything away,” I said. “You are. You’ve been throwing things away your whole life because you always think something better is coming. Well, guess what? Mason was the something better. And you gave him up.”

I hung up before she could respond. Mason was watching me when I set my phone down.

“Your sister is exhausting,” he said quietly.

I laughed even though nothing was funny.

“Yeah,” I said. “She really is.”

Christy crashed our dates. She told our family I manipulated her. She tried to make me choose between her and him like I was the villain in this story she created. Every single time she failed, he saw right through her.

I thought that would be the end of it. I thought she’d finally run out of moves. Then she went quiet. No calls, no texts, no surprise visits. That silence terrified me more than anything she’d done before because Christy doesn’t go silent. She doesn’t just give up.

A week passed with nothing. No ambushed dates, no family members texting me with concern. There were no hysterical voicemails at 2 a.m. My phone stayed quiet, and it made me more anxious than all the chaos combined.

“Maybe she’s finally done,” Mason said one night while we were cooking dinner together. “Maybe she realized it wasn’t working and moved on.”

“You don’t know, Christy,” I said, stirring the sauce with more force than necessary. “She doesn’t move on. She regroups.”

Days kept passing and still nothing. I started to wonder if maybe I was wrong. Maybe she really had exhausted herself. Maybe even Christy had a limit.

Then she texted me. It wasn’t a paragraph of guilt or manipulation. Just six words.

“Can we talk? Coffee tomorrow?”

I stared at the message for 10 minutes before responding. “Fine. 2 p.m.”

I told Mason about it that night and he offered to come with me. I said, “No. Whatever this was, I needed to face it alone.”

Christy was already at the coffee shop when I arrived. She was sitting at a corner table with a cup of tea in front of her. She had no makeup, and her hair was pulled back in a simple ponytail. She looked almost normal, almost human. It was unsettling.

“Thanks for coming,” she said as I sat down. Her voice was calm.

“What do you want, Christy?”

She took a slow sip of her tea and set the cup down carefully. “I wanted to apologize for everything,” she said. “For showing up at your dates, the family stuff, the texts to Mason, all of it. I was out of line and I’m sorry.”

I waited for the catch, the manipulation hidden inside the apology, but she just sat there looking at me. Her expression was one I’d never seen on her face before. Acceptance.

“I’ve had time to think,” she continued. “And I’ve made peace with how things are. You and Mason are together. The contract will be over soon. Whatever happens after that happens,” she shrugged like it didn’t matter. “I’m done fighting.”

“Just like that,” I said slowly. “You’re done.”

“Just like that,” she confirmed. She smiled, but it wasn’t her usual sharp smile. It was softer, almost sad.

“Enjoy him while you can, Bailey. You two seem happy. And when the month is over, we’ll figure out where everyone stands.” She tilted her head slightly. “Maybe Mason and I will work things out. Maybe we won’t, but I’m not going to keep making myself crazy over it.”

Something about the way she said, “Enjoy him while you can,” made my stomach turn. It was as if she knew something I didn’t. I had a feeling she was already counting down to something.

“Okay,” I said carefully. “Thanks for the apology.”

“Of course,” she stood up and grabbed her purse. “I’ll see you around, Bailey. Tell Mason I said hi.”

She walked out and I sat there for a long time trying to figure out why her being calm scared me more than her being unhinged.
