Firstly why can't you be together? And you could always talk to her and find out if she likes you as well...Jenny

well first shes 18 and im 15 and she has a boyfriend too and thats why we cant be together i guess
and i dont know what to say to her

Oh i see..Well this is a tuff one then because if you know she has a boyfriend then you cant really say anything to her...coz she will be like i got a boyfriend and it will be telling you something you already know. Try and be friends with her...that is really the only way you could be close to her...Jenny

i dont need to be close to her i just need to forget her and i dont know how thats why i posted the question

If you want to forget her..get away somewhere with your mates or go out and just have fun maybe meet some other girl thats really all i can suggest...good luck...Jenny
