I don't claim to be wise at all, just hyper-intelligent, so I'll give you some advice, bud:
NEVER OBSESS OVER A POTENTIAL GIRLFRIEND. I hope that doesn't sound rude or mean, but it is 100% true. I made that mistake when I had my very very first gf and that relationship didn't even make it a week. If you're crazy about her, that's fine, but the "crazy" part should be something calm, a relaxed and inviting appreciation of your crush.
Just be honest and tell her how you really feel. The worst she can do is say no, or not be interested. But take my word for it; you'll know when and if she accepts you.
Sunny taught me that. She knows we're meant to be together. You'll have the same luck, I know you will
