There's a boy which I think I love, he has a girlfriend but he acts like he likes me too.. sometimes and other times he makes me feel like I'm just pestering him and getting in the way of his relationship, what do I do? We had abit of a past with each other I don't know if that would make a difference, I'm 15 but I truly think I'm in love.

OK, so if he has a girlfriend, don't get too close to him, because youl piss her off. (you really don't want that) and sometimes if he acts like your in his way, your probably getting to close. (he has a girl friend) if you really love him, you won't be able to wait, but you have to, relationships at that age usually don't last that long, so if they do break up, and your friends, that's good, but if you love him you don't want to be like, a rebound relationship.
I hope you get your chance.
