My bf and I had an argument last night yet I didn't think it was an argument at all. I told him I was having a bad day, the previous day I had met with a DBT program psychologist and once again had to re-hash everything I felt and it brought up a lot of past trauma. He has never experienced mental health "issues" and doesn't get it. He has been one of my best friends for years before but I had strategically made sure he never saw me in my bad states. I tried to explain to him I just needed some reassurance but he kept mistaking it as me picking a fight for not getting enough attention. He had a paper due that night he was working on but he hardly spoke to me or even asked every now and then if I was doing okay. I tried to explain that that was all I was looking for but he kept being defensive and acting like I was attacking him. I completely broke down crying and was so frustrated that he didn't even want to hear about what I needed or try to understand. and then he said "I can't fix you" as though this whole time i was asking for that. I wasn't at all but that hurt so much because I just want support. I ended up leaving and haven't spoke to him since. In his mind he doesn't understand what i'm trying to express or why i'm the way i am. He knows I have BPD and told me when we first started dating that he is ok with that and knows what he is committing to. Yet when the time comes he just says how he is not good at this kind of stuff. I just want someone to want to support me and make me feel like i am worthy of love
