I really love this girl and would do anything for her but I found out that she only likes my brother and now I don't feel like going outside or doing anything with my brother or the girl I like. The bad thing is she never really liked me at all. What Should I Do? );

Ps she doesn't care that my brother has a girlfriend

Some people are just self-destructive like that. You kno someone is already attached and you still go after him even when there is someone who is worshipping you nearby. @OP, just forget them and try to find someone else

dis OP is a foool! U shud be happy she revealed or showed u her true colours! Why are u cryin over spilled milk? Nna na wa for u oh! Oya go ahead and beg her to date u. But let me warn u! Wen she break ur heart, i nor wan see u for nairaland oh! U hear?
