Is this love that I am feeling?

Love. Nobody understands it and I am not an exception, but I want to fall in love.Why because you are happy and that is something I have not been for a while. I think i may be falling in love with my best friend. He is great and funny and he treats me right but there is one problem, my cousin.She loves him so much and she thinks that they are made for eachother.She does not have ANY chance with him and I know what I am talknig about. Why?Because I don't think even I stand a chance.Every time I am onlline he writes something so yesterday I asked him if he has I girlfriend or even a girl he likes.He didn't want to tell me, but I am pretty sure he likes me. So guys what do you think I shoud do?Do I tell my cousin first or do I check my chances and then talk to her? Or shoud I just forget about him?
Lots of hugs and kisses,
