OK a few weeks ago I learned that this girl I always had a thing for had a crush on me recently, but didnt think I liked her, but that she thinks I'm hot. Well I started flirting with her alot more, but I didn't ask her out because a guy that I'm kindof friends with had just had a date with her and they were going to go out again, so I didn't want to piss of my friend, even though she was telling my friend to tell me to ask her out.

Well its been a few weeks now (4 to 5 atleast) and I got word from one of his closer friends that he doesnt really like her, so I'm pretty sure he will dump her soon. I know I'm a better on almost all levels than this guy, but what should I do to ensure that I am her first choice when he dumps her, or should I not even wait and try to move in on her a little now?
