You need to go out more dude. Push yourself into tougher situations, this shouldn't be your worst moment. Going out more will make you immune to this kind of shit and better equipped to handle it
Bear in mind that girls aren't ever attracted to just one guy. They're like us. If you see a hot girl and you're attracted does that necessarily mean you don't like the student girl any more? No. There's always a chance she'll reject you but don't reject yourself dude.
As far as this goes just pull the trigger. Do something or don't. Personally in your position I'd just forget it go out and find someone better, but if you like her the total chance of something happening unless you escalate = zero. Do this ASAP or don't bother, the longer you wait the outcome attached and in your own head you'll get. It sounds to me like you're a long way down that road anyway but hey...

Oh yeah, and fuck The Game, the stuff in there's manipulative and mega creepy.
