Well well. Isn't this an interesting story. Perhaps we will have to discuss it later. 

As for the OP, the general advice here is to talk with her. I disagree to an extent. Yes you should talk to her but only if you really want to. I know that in the past I have had crushes with various people, and thought I couldn't live without them but they pass. No doubt others here will have similar stories. If you really care, then you've already made introductions so why not just have a friendly chat? 

Next time on VGChartz: "Relationships are too hard."

How far does she actually live from you? Try to contact her via facebook in a non-enthusiastic way and exchange messages/comments. Converse for a bit. If that goes well and she seems interested in conversing with you, ask for her number to talk/text. If she doesn't seem interested in your conversations with her, don't bother.

I recommend pining for her until you find out she already has someone then get depressed for a couple years. After a couple years of therapy you'll find someone you'll settle for and live more or less happily ever after. You'll be telling this story to your kids when they fall hopelessly in love with someone too. Its pretty much the circle of life. You can ask almost everyone and all of them will have a name of someone they were crazy in love with but didn't get.

Send her a letter. I mean it.
Facebook, text, skype, none are personal enough.

You don't even need to make a full confession, start with something small and see if she responds.
I was also very shy, but it was my girlfriend who made the first move. I can't image what would have happened if it depended on me to do something. We probably wouldn't be together.

Build some courage, grab some pen and paper and start writing.

One state over doesn't seem too hard. My girlfriend lives on the opposite side of the planet.

This is actually great advice! You really should contact her in some way, If you barely see each other anymore the longer you wait the less likely anything will come of it. It's best to just contact her and whatever happens happens, but if you do nothing then you'll never be with her either way. I think an actual written letter would be a lot more personal, impactful and be given more attention and thought by her than just a message over facebook.

Send her a dick pic

Shit or get off the pot.... You'll soon learn to do it or move on. Make yourself presentable and take a swipe or leave it alone. Otherwise you're wasting your time...literally. 

GL op, give us update when the time comes
