Boyfriend & Anxiety

Ka

My boyfriend got upset with me tonight because i didn’t want to go with him to his friends house. (i still let him go obviously i wouldn’t make him stay home because of me). After he got home we got into an argument about it. I tried explaining to him i get uncomfortable around these certain friends and i get bad anxiety that i didn’t want to put myself in that situation and then have to make an excuse up after 20 minutes of being there as to why i want to leave. He doesn’t understand he thinks i just don’t want to go with him anywhere, he doesn’t understand my anxiety and won’t even try to. It’s really frustrating and i don’t know what to do.
