Is OTHER wrong in the post ? POST : The gatherings are usually birthday celebrations with other close friends. It hasn't happened, but when it does (and there's a huge chance it will) she would go. This guy used to be her best friend and one time at a Christmas party (with the same set of people) they were both drunk and almost had sex. She tells me she regrets it but they never talked about it and both acts as if it never happened. She had a different boyfriend at the time and he didn't find out about it at all (they broke up due to different reasons). Fast forward to today, the thought of her in the same situation with alcohol and the guy gets me all irrational and overthinking. I of course don't want her to miss out on these reunions with friends but I just can't help not being afraid she might do the same to me what she did with her ex.
