<human>: Can you give me a shortened version of the text?

So a girl I really like, and who I've come to the conclusion kinda likes me, is going to a party next Wednesday, the same I'm going to. I need all the advice I can get. I met her a few months ago and we've written a lot, but only about big things we both were at, like a party or exam. Whenever we write I tend to do good (that sounded dumb, but you get the idea) but whenever we're actually together things just go downhill. I'm not normally awkward around other persons, but this girl, man, I just don't wanna fuck anything up. 

We're mostly together at parties, but I never know what to say when I encounter her. She also seems kind of rejective whenever we're in person, probably because of my stupid behaviour, but not on text. 

The thing is; next year, two months from now, I'm going away for a whole year, and as selfish as it may sound; it wouldn't feel right without having kissing her at least once. But I can't even talk to her. She's also very shy.
<bot>: I like a girl. We're not going to meet a lot in the future. She's shy, but probably likes me a little. How can I soften her up? How much do I write to her before Wednesday?
