Was I wrong

Jillian

My boyfriends mom was trying to get a piece of cake and my bfs brother is completely drunk so he’s obnoxious and rude so I told him to have another drink and relax. I wasn’t trying to be rude or anything. Then he started being nasty to me and said he knows something that will ruin my life and down pour on me.. ( he works at cvs so he knows all my personal issues and what’s medication I’m on) was I wrong for jokingly saying that to him
