Firstly my bf hasn t been yet diagnosed with BPD but he has alot of matches with its symptoms. His parents are divorced since childhood and he hates his father and he also has a stepdad. He has alot of mood swings within a whole day where he can be loving, caring and cute then the next day changes to a vulgar man who shuts himself up , refuses to tell what s wrong, he keeps his problems to himself only, he acts as if he hates all people and pushes me away with no reason. He played with me the push & pull method for a couple of times. When he gets back , ,he acts as if nothing happened and I think he keeps faking his emotions for a while and when he cant do it anymore, he distances himself only from his loved one and acts normal with other people. he knows he is emotionally unstable but I cant identify what I m dealing with, so is it really Bpd or what? thank you
