AITAH for not being emotionally invested in my relationship since my wife opened our relationship a year ago?

The Proposal and The Rules

My wife (29F) and I (29M) have been married for 4 years, and we’ve been together for almost 17 years. We’re each other’s first and only relationship.

We also have a 9 year old son.

Last year, my wife brought up opening the relationship. We’re both very open with each other, and we don’t hide anything from each other. She understood it was a very sensitive topic, and she didn’t force anything.

She said she never had the chance to explore or have sex with anyone else, and she just wanted to give it a try. I was devastated but I heard her out and told her I needed a few days to process it.

After a few days, I told her I would be ok with it, and I laid out a few ground rules. She had to get regularly tested, she had to have her partner get tested, and not to bringing anyone at home.

I also told her not to talk about her dates or hookups with me as I did not want to know about it. My wife happily accepted all of the conditions, but she also apologized a lot.

She told me she’ll do anything for me the rest of our lives for being so understanding of this.
