So two years ago I fell in love with this girl in my class. I couldn't stop thinking about her. I never told her but I think she noticed. I couldn't concentrate at school somehow I passed it that year. So it was a hard year at school for me but eventually I got over her. Two weeks ago I saw her in a disco, we were dancing and we kissed at the dance floor we didn't talk very much. But like 2 days after that I started to feel things for her. Now 2 weeks later I'm totally and completely in love with her again. Can't concentrate anymore and stuff. I know, I should just tell her, but that's definitely not going to happen. How can I make her notice that I really like her. She's not in my class anymore, we aren't even in the same school anymore. I'm 17 she is 16. So my question somebody with a similar problem, or people with tips?
