Is it normal to think i should just give up?

There's a guy I like but don't really know so for the last few days we've just talked on the facebook chat because I just want even a tiny chance with him and today I talked with him for a while about things and then facebook messed up and he left and on his pictures I saw that there's a whole big album with like 90 pictures of him and this one girl. They're obviously perfect for each other so oh well I had no chance anyway.
It's just that he actually makes me happy. He makes me forget about everything which is something I've never really had before. But I guess it doesn't matter. I'm not in love.. Just like him... But he actually loves her.
Always want what I can't have!
