What does this girl want from me...!?? *VERY CONFUSED*

Rebound/pity ****.
Her bf is messing her around so she falls back onto the 'caring' guy who will 'always be there for her'.
You want my advice? Get the **** away from her in a relationship context.

Hey people!

Basically, me and my uni housemates have just finished uni - last night out a few weeks ago, one of my female mates, btw i'm male, got a bit touchy feely with me, and we were linking arms etc, and generally having fun!

Recently, in a group we went on holiday, and things were great we got on really well, and on the last day I drove her back on my own - she suggested that we stop off in a town on the way back for dinner, and have a wander around the town - we did this - often were joking and messing around, she would randomly try and scare me and jump on my shoulders etc.

Now this sounds great but the prob is she has a boyfriend - she was slagging him off a bit during the holiday, and wasn't in contact with him at all.

So, I don't see where I stand in this scenario - I recently havn't had luck with girls, and she is aware of this and always says that i'm a really nice guy.

Where do i take this...does she actually like me, and do I tell her I like her? I really dont want to ruin the friendship we have though.

Anybody else here in a similar scenario?
Advice would be much appreciated!

Many thanks.
