All over me and suddenly gone cold!!

anon for obvious reasons
rather it is deleted thanks

Cut the long story short I met a girl on campus during the day through an acquaintance (in the library of all places)

Unfortunately my friends (and consequently me) have a reputation as the biggest cu*ts on campus and being generally obnoxious spoilt "lads".

We got talking on a night out the next day, and she mentioned how her friends had pointed me out as someone she should definitely stay away from. The girl herself is one of those rah rah arrogant types (like most people at my uni) and she was actually quite good fun to talk to- as well as very very hot (yeah im shallow)

I ended up pulling her all night andwent back to mine but nothing much happened.

We text back and forth for a week and the next week the same happened, we both came back to mine and spent the night with her- nothing too sexual happened , she left early morning. I pushed it a little at one point but when she made it clear she wouldn't put out YET I eased off.

We kept texting back and forth but she seemed a bit off with me and I kind of stopped texting her- knowing I'd see her soon a night out. However this time - she was really cold and I later saw her pull some guy. As she pulled him she made sure I was watching and made sure she did it in front of me- we made alot of eye contact in the process.

Im not that fussed in the scheme of things- just wondering what the hell happened. This was on the last night of term and we've broken up for christmas but Im not sure why she did that. Even her friends looked surprised. I'd say shes a whore but if anything she seemed quite frigid. Generally bemused
