Girl i was talking to (came over multiple times, escalated high until she claimed to be prudish and wants to change) cancelled on me last week and went to another guys place (found out through groupchat)

Whatever wasnt tripping especially since she talked to me the next day to get something to eat but this time i was more IDGAF attitude. However since then she stopped talking to me completely and immediately leaves after class.

I would say fuck it and game other bitches in the club but problem is, she is the house head of the club. We have our first meeting tonight and there will be parties in the future. How can I not seem like a loser that got tossed but also game other chicks without her popularity/status getting in the way?
