Is this girl worth it?

I'm going abroad next semester and just started hanging out with a great girl. She is a senior and will have graduated by the time I get back. She's totally great-- funny, smart, pretty, and mostly what I think I'd like to find in a girl. She just got out of a serious (two year) relationship and seems pretty upset about what happened with the guy (he was a real jerk).

So what's my play? Here is another interesting part of this-- she's a virgin. She dated this guy for like two years and they never had sex. Her dad is a minister. We've had some interested conversations about this topic and I guess I'm a little baffled by the whole thing. Should I just keep letting her cook for me and have a great time without anything romantic happening? What do you people think?
