AIO, wife didn’t share close male friend once had feelings

My wife didn’t share before/after marriage that her close male friend (say Mike) once had feelings for her, saw her more than just a friend. She shared only AFTER I raised my suspicions. I would have probably been buried six feet under without knowing this, honestly.

Context: They are very close, known for maybe 10 years. They have done solo/group lunches/dinner, and done overnight tours at beach resorts with a mix of male/female friends during the college years.

So in the past she stopped talking to Mike for some time once she found out, but then they reunited. She continued talking/hanging out with him. She invited him to the pre-wedding, wedding, and post-wedding events. All without my knowledge that Mike once had intimate feelings for her. We three were all in the same room at the wedding night!!!

I feel like a fool/idiot and maybe disgusted that Mike was at our wedding and in the hotel room that night (Mike dropped us off and helped bring stuff to the room).

My main anger is that she didn’t share this important detail before marriage. She only shared that they were close, nothing more in details. She rarely mentioned him, even when talking about trips they had gone together (+ their mutual friends) in the past.

I feel by not sharing this, she took decisions away from me before getting married. Possibly I would have been fine as long as she continued to maintain her boundary with Mike or maybe I could have asked her to not invite him to the wedding and/or the hotel room. Or I could have said no to everything. But yeah, she took all that away from me.

If she wasn’t still in contact with him, I wouldn’t have cared if she shared this or not. I feel broken. I don’t know what to do.

AIO? Is it a silly thing to worry? Should she have mentioned this before marriage? Importantly, how would you feel if you were in my shoes?
