My boyfriend of 5 years has a close female friend that he regularly meets up with for dinner. When I asked if I could meet her he said that he would really like us to meet but when he asked her she told him she didn’t want to meet me as she is socially awkward. It has caused arguments between us as I feel uncomfortable with them meeting up now. She even refuses to double date with us when she is seeing a guy. Every-time we we argue about this situation my boyfriend gets defensive and says I’m trying to make him choose between me and her which I am not but I just feel like she doesn’t want to accept me being his girlfriend due to all the excuses about not meeting me. I don’t know how to resolve this situation?
