when you finally reach it, what next?

So, I've studied the art of pickup for about two years now. What I've never studied is how to keep a relationship going. I've reached the point of pickup that every PUA is looking for (at least a majority of them), the perfect girl. Ofcourse theres some circumstances that goes with this girl but, as a person and not including her past or future, I really like her. but the thing with me is that i'm terrible with relationships, and I am a little afraid that if this girl actually begins to work out that she'll be gone anyways because shes leaving for college. its a fucked up situation and this is a reason falling for someone should be the right person otherwise, well you know how it ends...
ugh shitty. anyways, summary: I like a girl, know pickup better than relationships, shitty feeling aka butterflys.
