You're not wrong though. Spoiler alert: it's totally ok to be friends with your... friends. It's ok to be friends with your exes! Nobody here did anything wrong. You (maybe a bit bluntly) pointed out a double standard, which is a good thing! Way to maintain your (totally acceptable and healthy) boundaries, friend! It's dumb as shit to get jealous over exes - they're exes for a reason. It's even more dumb as shit to get jealous over people you kinda liked but never got with as a teenager, because for most people that's a lot of their friend group growing up and many of those friendships carry over to adulthood. I can think of a great many women off the top of my head that I had crushes on in high school and am still tight with in my mid 30s and I'm happy to see them married and having kids. That's just basic emotional maturity. Honestly the only TIFU I see here is "it bothers me to know she's been with others." Like bro, everyone has a history, sex is literally just sex, virginity has no physical metric and even less value, it's just some stupid concept from back when humans knew even less about themselves than we do now (the notion that someone is "tainted" because they have experience is dumb as fuck). Apologize for hurting her feelings but have a serious talk about jealousy and how toxic it is, because if she's afraid of your childhood friends she's not gonna be comfortable with you talking to women in general, and that is toxic as fuck.
