Should I just avoid her?

[Anonymous]

So there's this girl I met last year but I've only met her twice and talk on Facebook at least once a week.
2 weeks ago she confided in me telling me she likes this guy who she is not sure that he likes her and that she doesn't really want to be in a relationship with but only wants him. (Btw the guy wasn't me, she gave me a name and showed me screenshots of texts between them)

Anyway she asked last night if she wanted to meet up and I drove to hers, picked her up and drove around for a bit when she started to kiss me and it lead to sex.
This was unexpected but I did find her attractive.

She hasn't attempted to text me or Facebook me since last night but I saw her Facebook status from a few hours ago saying "I have too much pride to wait around for you forever". From the comments I've read, I can safely say it's not me since it refers to the guy going for her friends.
Did she just use me for sex?
Not that I'm much phased by it since I don't have any committed feelings towards her,

I'm sorry but it sounds like she regrets what happened between you. Her avoiding you seems like her way of saying : 'this never happened let's forget about it'. I think she was probably upset at the guy for rejecting her and needed to feel 'better'/wanted' by someone. You were around. You went for it. You helpt boosting her ego. And now, she realizes it wasn't what she wanted.

Yes I think she did use you for sex, not just for the physical pleasure but also for an ego boost. She wanted to feel attractive. Sorry she used you like that, but it sounds like you didn't mind haha! ;) Would you look at mine please? Thanks! www.girlsaskguys.com/.../q1312996-was-it-more-about-me-or-the-parents

How do you not have the balls to phone or text her since you have had sex?
I would tell her straight, is she using or not?
You have sex and then go back to talking about another guy.
Just friggin phone her and ask what this situation actually is and ask her to clarify.
I would totally not have any nerves over a girl I've screwed, My nerves evaporate after that.
