I like this girl but she doesn't notice me and barely talkes to me. I don't want to be hurt but I don't know what to do? Any advice
My advice to you is that you try your best to get her to notice you, don't become a stalker but try to talk to her. And then if that don't work, you move on.
my personal belief is that you should talk to someone you like. so, just start with an easy question, like "can I borrow your ______" or "hey, did you know the homework for _______?" and stuff like that. After the intial contact, try to just smile at her in the hall or something. Wait to see how she reacts, and if she maybe initiates a conversation, try talking to her again, but, if she doesn't ... get a new plan
