Search Results: messing around with her boyfriend

So there's this girl I met in one of my lectures in college (we are both freshmen), and things started to hit off. We first started by sitting next to each other, than exchanging numbers, than hanging out around campus and even skipping lecture to hang out. Clearly we are interested in each other. But there is one problem. She has a boyfriend. Yes. A boyfriend.. I know I'm in the wrong to be messing with someone's girl but in my defense she never mentioned him until I asked. And when I did, her immediate response was "yeah, well kind of.. we fight a lot" and went on to tell me that he went to a college in a different state. She never mentioned him again on her own until the next time we hung out I had discretely brought it up again. And to my surprise she begin to complain about him, calling him crazy and saying that he was too protective which is why they argued a lot. She even said that he wasn't the type of guy she wanted to marry. So I don't know if I'm comprehending this the right way, but I took that as 'We aren't staying together for long, I am interested in you'. But I truly don't know what to do. I mean, this girl is awesome, we have a lot in common and she's very genuine. One of the few girls that actually make me nervous. There is this haunted house thing my college is hosting and I was thinking about asking her to go with me, but this past weekend her boyfriend came into town and today she acted a little differently, a little less flirty than usual, but I also know she got really little sleep because I got a text from her at 2:30 in the morning and our lecture is at 9. Any advice on what my next step should be? Thanks yall.
