I want to describe my biggest "quirk". Does it fit in with BPD?

I really like emotionally hurting people. Usually women because it's easier. Common examples: getting into LTRs (both men and women), and then ghosting them once theyve fallen in love. Standing people up on dates. Picking just 1 person to give the silent treatment to in a group (like in a work or friends setting) while being friendly with everyone else.

These are all my best memories. I have a warm, happy feeling when I think back on them, or read my messages of peoples responses to my rejections/ghostings/etc.

I've been internet diagnosed as a sociopath but I DEFINITELY have empathy. I have concluded it's probably nothing, just a sadistic side of me. My question is, do any other BPD people here share these traits of mine? Just want to see if I really could have it.

I am 30, male.
