My partner and I have had very clear boundaries when it comes to other men / women and what we agree is appropriate / would class as betrayal from the start (I have been cheated on in the past so didn’t want any room for ambiguity).
One Saturday we had a group of friends over for a night on the town and then all headed back to ours for an after party. I was pretty merry and my partner was very drunk.
We were all dancing in the living room when my partner grabbed the breasts of one of our friends from behind and imitated having sex with her. She frowned and moved away, at which point he put his hand round her throat (very gently and in a sexually suggestive manner, not aggressively) - this is a him and I thing in the bedroom. The woman’s partner was in the room but did not see.
I felt pretty sick in the moment and hurt and so when he went to our kitchen alone I followed him and explained that I felt upset about what he had done - I broached this very calmly as he has a tendency of getting rather loud and essentially airing our business if we row when he’s drunk, which mortifies me.
He responded by telling me to stop ruining his night and to “fuck off and entertain our guests,” before slamming the door behind me (I had started to leave the room as he was shouting at me and I was really embarrassed).
Shortly after, the evening ended and I left him to sleep off the drink. The next morning I reminded him what he had done and he was mortified. He said that she is a very platonic friend and he just saw it as messing around. I must say that he is otherwise a very good man (I’m aware this story might suggest otherwise) and this is the first and only “fuck up” in this respect, but I now get huge anxiety when we have people over with drinking as the main activity, and the thought of him going out drinking without me fills me with dread, the rare occasion he does go out without me I cause issue over it as a result and he’s starting to feel trapped.
I feel horrible about it, but also I still carry so much hurt. AIBU? Please be kind!
