How do I get over this girl and move on? (long question)?

Don't think so hard about it. What will she be to you in 5 years? She might not be anything, you might even forget her! Move on with your life because you can, and find someone who wants to talk to you, who wants to be with you. There are a lot of beautiful women in the world and if you're the right guy for them, then she's the right girl for you. :)
