Hi guys. I have been with my partner for almost 3 years. He has bpd and other mental health issues. I have bipolar and other mental health issues as well. I have been supporting him, loving him and being there anyway I can. I have been in therapy and on medication for a while now. I have been trying to convince him to go to therapy because I understand that I cannot help him and he needs to figure it out. He’s going to start therapy soon. I’ve recently found out that he has a “FP” or favorite person for a couple of months now. His favorite person is woman and I know it’s not sexual, but platonic (we are gay), however all he does is talk about her. To him she can do no wrong and every action or feeling she has affects him severely which affects our relationship. For example the other day she said something to him that rubbed him the wrong way and his anxiety was at 110% and was distant, irritable and anxious with me. I know he can’t help it, and I know logically it’s platonic but I don’t know how to cope with it. The other day my parents made plans for dinner with us and based on our schedule we couldn’t change it and he was already going to hang out with her. He ended up hanging out with her. I guess it’s okay since he already had plans with her but I’m upset he chose her over me. It drives me fucking nuts and makes me feel like second fiddle. I know it’s an obsessive infatuation and it will fade but he feels so distant so indifferent. If he’s happy he had a good day with her and If he is miserable it’s because something happened with her. I was hoping you guys can offer some tips or advice to help me cope.
