Hi everyone, I was recently diagnosed with bpd but have known for a while. The guy I am in a relationship with lied to me about his flat mate back in the beginning of our relationship. He told me she was just his flat mate but actually she is his ex fiancé. The thing is I don’t actually care that much about that as he was actively trying to leave the house they shared. The problem is he lied to me after I had opened up about how lying broke down one of my past relationships. I really struggle with trusting as it is and feel stuck. I don’t want to leave him but I don’t know how to feel trust towards him again. I feel like the bpd is partially what’s making it so hard because I cannot leave the subject alone. He has given me his passwords to everything and is patient but it doesn’t change what he did in the beginning.  I would appreciate any advice except for telling me to leave him. 

Thank you
