Charlie you should probably leave...you dropped some blood in the shark tank and they are always hungry.
You must have left something out. Why is she this creeped out by you? Why did she ban you on FB, and why does she feel weird around you?
"Edit: a little more. I've gotten her to crack up a time or two, and she viewed my LinkedIn profile when I connected with a fellow co-worker. "
And I find this particularly lame. Almost Spatial Mind lame. If after all this time you think making her laugh a couple of times is something even worth mentioning... Also the LinkedIn profile... You are the creepy stalker kind of guy, aren't you. Even the fact that you came to seek advice to seduce her on a sociopath forum if pretty fucked up. Poor girl.
Charlie,
You are a fucking creeper, and in no way a sociopath. A sociopath does not need to find common interests (nor do they usually have them) to connect to someone. We find pleasure in challenging manipulation, which sometimes involves people who have no common interests, but are useful to us.
Just give the girl a fucking break and leave her be. Ignore JHawk by the way, he's a douche empath.
