Had a short-lived fling with this girl a couple of weeks ago. Met her at a concert, she came back to mine and the next 2 days we banged so many times. Naively let her stay over for too long, was way too intimate with her and I developed oneitis because she was exactly my type and we shared a lot of interests.

Got ghosted out of nowhere after she left my house the morning after our second date a week later, even though she was acting really into me throughout. Honestly, I have struggled to get her out of my head whilst trying to game other girls.

Anyway, I’m going to this club this weekend for this event, and I know she said she was going.

I've accepted I need to move on but when I see her how do I react? Any way I could make her regret her decision?

If she tries to converse with me about it, or apologizes what do I say?(I sense she’s the type of person who might try to explain herself). Obviously I don’t want to appear butthurt, and I also don’t want to appear like I’m putting on an act by acting too ‘aloof’

Thanks
