Help!!!!

Okay ladies, me and my SO have been having major issues these past few days. We talked them out literally at 5:35am and he brings to my attention he doesn’t want me being friendly with his friends when they are around. “ You shouldn’t be smiling, joking none of that.” So I bring to his attention that he needs to talk to his friends because I am NEVER the one that initiates conversation or anything I just respond. He then says it’s my fault be rude but me having sever anxiety and depression I feel as though I don’t want to here them telling or joking about how I’m rude. He calls it flirting but to me they call me sister and him brother. I don’t know what to do... he also told me not to tell them to stop talking to me sooooo.... basically I wanna know am I wrong?
