so, basically I got to meet this girl on facebook (she's 10 years younger than me, I'm 29, she's 19), she saw me like a picture of her on a mutual friend's profile and sent me a friend request. we got into each other pretty quickly; conversation was nice and all, but I found out she has a relationship with a fuckin' narc (I'm almost sure she's either BPD or HPD), so she constantly is changing her behavior and talking about how shitty her life is... after a few days of non-committed talk she asked me my phone number, started talking to me via whatsapp, things got hot pretty quickly, she sent me all kinds of nude pictures, spend days saying she wanted to fuck my brains out and all that shit... we met on a sunday, kissed when she was leaving (there were other people around and I don't like to play my cards in public, lol), then got to meet 2 times after that, made out and everything, but she kept avoiding coming back to my home and after the second time we made out she said she was feeling bad about cheating on her (non)-boyfriend... after that I went from being cool to overplaying my hand, I told her several times I like her (never love) and that I want her to feel good with me and all that beta bullshit... I kept trying to talk about it and explaining myself (beta motherfucker) and inevitably ended up throwing her off... she still contacts me but the sext talk pretty much stopped, she tells me she doesn't wanna hurt me (she can't) and that she wants to be a friend that fucks me here and there... yesterday she told me she wanted to be my friend but I told her I'd never lose an oppportunity to hit on her, so she knew what she was getting into... my question is: am I being shit tested? did I overplay my hand? what do I do? I wanna fuck her, I don't give a shit about what happens next, I just feel I need to fuck this girl, she aroused to a level beyond comprehension... LOL. should I just stop reaching her? should I tell her to go fuck herself? what next?

PS: I made a post earlier but I think it was too long, so I decided to make this one...
