I've been thinking for a while...

I was in a scenario where my canned material and sort of "fake" personality got a girl half-interested. She basically told me she liked me but she was not emotionally available. Being the AFC I was back then, I thought it was some shit test and just escalated anyways. I didn't let the attraction build up. We did end up having sex, but it was more like FWB sex and not BF/GF sex. You'd think after sex, she would be more emotionally attached but because I pushed her so much, it killed any attraction she had for me.

Looking at it retrospectively, what should I have done when she told me she liked me but she was not over her ex?

With my experience now, I should have probably just said "whatever, let's just enjoy each other's company" and while I tell her there is nothing going on, I DO escalate physically, maybe heavy touching etc.

Problem with most pickup material is that it adds a facade to compensate for weak identity. You need a solid core identity as Tyler Durden speaks of to actually be the man you portray yourself to be. Once you've reached this level, which takes a lot of work and self-discovery, picking up women will be so simple its only an afterthought.

Sometimes girls regret sex....and this comes from not building enough comfort. Mystery speaks on this...
