Getting married soon, I (29f) and my fiancé (32M) have been together for almost 7 years. I found out last year that a girl in our mutual friend group who I always was very close with used to hook up with my fiancé on and off for years before we met (in college). He didn’t tell me up until this point bc I was adamant about not wanting to know about his past (I ** thought ** I just didn’t care, the past is the past) but this girl and I were pretty good friends for a while before she moved to a different state. We’ve since lost touch and after finding out that they used to casually “see” each other, I really don’t care to have her in my life and actually care more about his past than I initially thought I did (I can hold myself accountable for that tho!) Long story short, fiancé and her are still friends and keep in touch. He says it’s not weird, and she’s moved on also, but I can’t help but fstow that she and him used to be involved like that. He wants to invite her and her SO to our wedding seeing as though they’re still close , but I don’t. AITAH for setting a boundary for not wanting her there given that they’ve been sexually involved? No one from my past will be invited for obvious reasons so I feel it’s only fair, but it’s his wedding too so idk what to do.

TLDR: Fiancè and his f*** buddy from college are still friends, he wants to invite her to our wedding and I don’t, despite also once being friends with her. AITAH?
