would you be mad

my two friends got into a verbal fight and I asked one of them if she was okay and she was like don’t fucking annoy me rn fuck off and I was like idk who you’re talking to like that I did nothing and my boyfriend said right infront of her to ME “do u ever know how to shut up or do u just mouth off to anyone” and then 20 minutes later I find him taking shots with her and 2 other ppl giggling and having fun after I got disrespected at a party infront of everyone. and he’s saying i’m over reacting.. 1 i’m hurt 2 i’m EMBARRASSED. would u be mad??
