Wat if u like a girl but she has a crush on another guy?

Well, be the decent guy and exit gracefully. If you want her to like you, then be her friend first but do make sure that you do not fall in love with her seriously yet. If her crush for the other guy is very strong, then help her get him... Because if you love a person seriously, then you do not care about what you want... you would only care about what she wants.. If the crush is not too strong, then be her friend and show her how you are a good guy for her and how you can make her happy and fulfill all her dreams. Good luck..

This is a nice question. This happens sometimes in life. Well, I will leave the girl free, even if I like her so much and I have not expressed my love...because the world has so many girls and I am confident that I can find another nice girl who will love me. Lol.

You should just be a good friend to her at first. If she likes you very much she may come to you. But you should be cautious there. Because she came to you as you are better than her previous guy, she may go away from you if she finds someone more better than you. But if she really loves another guy before you, she doesn't leave him and come to you because loving someone is something like they will be forever even they found a better person. In that case be a good friend to her and help her and her love to succeed.
