Am i wrong or is he being insecure?

Stella

So during a friend’s wedding after-party one of her cousin sat next to me and tried to get me drunk. At first the bride was sitting across from me and had strike a conversation between us, so i chatted a bit to accompany him (he was from abroad). He started to get drunk afterwards and He was being really flirty even though he’s married and ignored the fact that I have a boyfriend. I clearly told him that I’m devoted to my bf albeit the fact that he’s 900 miles away from me, but he was drunk and kept trying to convince me that whatever happens that night don’t happen if we don’t remember it. I was sat stuck in the middle between people in a long table, there were other tables behind my chair so i couldn’t just get up since there were no space left and i was a bit tipsy but couldn’t really get away from him. I told him to go after my single friend instead and once he did i quickly escaped. I told this to my bf after i reached home, but he said he was disappointed in me. He’s blaming me for his advances citing me being ‘too friendly’ and that if this happen for a second time he’d broke up with me. Now every time i told him i’m going out with my friends he gets uneasy and worried that i wouldn’t be able to “take care of myself”. I’m 25 years old grown woman, and I think I handled the situation well. I didn’t flirt back with him and had told my bf i’d drink a bit and he said okay but then got upset when i got a bit tipsy.

In the past i was a bit popular( me being older, having a career and several guys were after me at the same time) he said several of my friends were after me too but i was too dense to notice. There were cases where some guys were really into me to the point of obsessive stalking and my bf is using this to justify his worries. Well, i think he’s being insecure esp after his ex of 4 years cheated and he broke up with her. I have always been a one guy lady and i hate keeping in touch with people except for him. He really broke my heart. He’s been a wonderful and supporting bf, the best yet actually so it’d be a bummer to lose him. I tried to explain to him but he insisted i was in the wrong for not getting away from the drunk man sooner. Now every time i tried to discuss this subject he said i’m being stubborn and that “i can’t always be right”. We rarely argue tho. :(
