Is AUTHOR wrong in the post ? POST : 
Friday night I (22f) am going out with my boyfriend (25f) and his friends (23-25) 2 “couples” join us and some single guys. So night is going well and we come back home to play a game. This girl who is “dating” my boyfriends best friend is very buddy buddy with my boyfriend (this is my first time meeting her and hearing her name). Throughout the night we’re friendly until she pulls me aside and asks if I have a problem with her being friends with my boyfriend. At this point I honestly did not. Then we play a game and she makes her players name my boyfriends name loves her name. At this point I’m pissed. She asked me if I had a problem bc she noticed I was being quiet and then I felt she caused a problem. She was also making small jokes with my boyfriend. At this point I removed myself from the game and went to bed for the night. My boyfriend thinks I’m the asshole for being over dramatic. But I feel that if the girl really thought I had a problem with her at first why would she make her name like that in the game knowing it would cause a problem. Am I the asshole for leaving the game? 

Also my boyfriend later talked to me and said they’ve been friends since they were kids (10+ years) and she’s really into his friend. I just feel like for the first time meeting me she would be more respectful to my relationship.
