Do u think she might like me?

First off, don't be so hard on yourself. You have practically answered your own question....I promise I wouldn't remember what you had to drink a week later if I was not interested. Something else to think about, she didnt have to invite you to the club with her and her friend, and she totally hinted about her upcoming birthday. You should have asked for her # instead of telling her that you would see her in school.....go back to the buffet!
