First off, I'm 21 and I would say above average-looking. The girl I'm dating is 20 and goes to the same college, and is no more than HB7 at best. Every party where we both have attended at the same time, we've kissed. At first, I wasn't particularly interested in her, but now I want to be in a monogamous relationship with her and I fear I'm suffering from one-itis, although I am sleeping with other girls. We have been on three alone-dates together, and kiss all the time, but we've never had sex..

Now.. I know she thinks I'm attractive, and I also know she has a great time with me. But I'm losing it. I don't know what to do next. She is regularly talking to me on msn/facebook chat but its mostly everyday stuff.. How do I get her to chase me? She just left my place (our third date, she came late and I thought she was going to flake but said her earlier plans took a little longer time than expected), and I don't know if I should try to avoid speaking to her on msn/facebook and getting her to text me instead? Any ideas? I really like this girl...

Thanks in advance!
