You are so young. You have a whole life ahead of you to experience love. She might be your breakthrough relationship, whether successful or not. It's opened your mind and your heart. That is a very good thing.
There is something about writing your feelings that is almost more revealing than speaking. It allows you more eloquence. I think it's a very powerful communication that should never be underestimated. I've known 4 couples who met on the internet and are now happily married. Heck, people are meeting each other through those internet dating services, probably with a heck of a lot less communication between them. Certainly not two years!
This must be really scary, but you definitely have a rooting section.
