I mostly heard that the borderlines are mostly from females compared to males but....
Can a BPD family can be passed on to a family? I have a feeling my ex may be diagnosed with BPD and possibly Narcissistic that could be passed from his mom and grandfather [mom's side]...
I'm not sure if I can explain the whole story though if I'm allowed... I still care about him but he has this "change of feelings/moods" with me. Dumped 3 times apparently. He doesn't care how hurt I am or the relationship, but a few months later he may develop feelings for me again [just like before].
The saddest part is when he gets "nice nice" again, it'll be hard to resist since he's really caring, compassionate, and always there to help and listen.... But once something triggers him boom... Complete opposite. He doesn't care, avoids me, treats me like a "jerkass" and so on. And it's killing me mentally...

Err again.. I'm not sure if I'm allowed to explain the whole situation... It'll be a very long story if I do.
