Chick move, what do you think?

[Matt Williams]

OK, so I turned 30 today.(10/5)
Anyway, I invited this hot chick I know to a local bar with me and my buddies. She is 25. As far as I know, she had been dating this dude since college.(around 21). She is absolutely smoking. My roomate grades her a 9.5 and he rates Cameron Diaz a 7.0. So for him to rate her that high is saying something. Anyway, we go to talking about her ex-boyfried. I was buddies w/ him before i was friends with her. I told her that it was his loss to lose her and that if she had no boyfriend, I was ask her out. We have fooled around, but nothing major. She knows I have the hots for her, and I know she has the hots for me but is dating a guy for almost 5 years. What is my next move?
