I really like this girl but i dont know if she likes me back?

She may or may not. Sorry and I hope I'm not crushing you by saying don't get your hopes up. I have a friend like that and he is a bit of a player! lol XD I heard about this person. She said she was moving to the person and that's how she found out he liked her. Of course you can ask her if she likes you but it might be embarrassing to have to admit it. Tell her how you feel about her. Good luck! ;)
