Hello dear Zakmak,
Thanks for your story, pretty interesting story man! Sounds pretty romantic that you did make out with her after a one itis from a half year! Well i will tell you what her reaction means.
She is clearly into you, don't worry about that. When a human being is drunk it always tells the truth ^^ Don't forget that :p The reaction has nothing to do with you and her feelings for you. She is just a shame of herself because she didn't make out with you when she wasn't drunk and she did when she was drunk :p Just shame man.
On the question if there is a chance to get in a relationship with this girl? Well that's hard to tell. You probably want it because of your one itis :p But the main thing is do not let her notice that you need her. Just act very cool about the whole situation. Don't try to discuss this stuff with her on msn hotmail or textmess. Talk with her about it when you 2 are together. Untill that time just act cool. Talk about cool stuff.
I hope this will help you man

I feel for you. But remeber. Don't get hurt if she don't want to be in a long distance relationship with you. So try to feel that you don't need her because there is a chance you will get hurt

But remeber, there are plenty enough of fish in the sea
Goodluck!
