What to do with crazy quasi-ex that I still want, has LJBF'd me

[tafakna]

The next weekend, after my epiphany, again with her bf there, she bit my face, arms, back, gave me a hickey, jumped on me in her bed and said she knew how much I wanted to **** her, and then specifically gave her bf a bj in front of me, to make me jealous. I drunkenly slapped her in a quasi-playful way (not hard, but in a "I'm not your ***** and this was inappropriate"), she slapped me back, and gave me the most evil, satisfied grin ever. She also gave the same grin to me right before I left. We said no words, but she knew she got to me.

I've read this a couple of times. A lot of what you say its a textbook case of acting AFC and its consequences. You were clingy from the start, and there's so little respect in the relationship that it would take months/years to fix it.

A LOT of things don't fit in how these things play out.

I see only a SINGLE explanation, and I'm dead serious: she is entertaining the idea of having a threesome, her bf is ok with it, and you fit perfectly like the third party.

Her evil grin, was because she felt she was getting to you and getting closer to her goal.

Seriously, there's no other explanation here.
