So here's the situation:
Friend of mine has a girl he's obsessed with, she comes down for the weekend and he asks me not to "be charming"
I always go for challenging girls and so this is immediately a green light for me.
She comes down, I do what I usually do and a week later we're doing everything but f-closing (all the while keeping it under wraps from our friends). This happens for a few days then she gets really busy or something to that effect and I start joking with her saying she's always doing stuff without me. Unbeknown to me she's taking this all like I'm seriously accusing her of neglecting me and so after about a week she says "we're done" and pulled the whole ljbf thing.

What I need advice on is how to handle this. I've been in this situation before and have been able to bring them back, but this girls different because she's really adamant about not taking shit from people, and that's how she feels I was treating her.

I've been thinking about not contacting her for a while and then coming back aggressively, she seems to like that.

What do you all think?
