This thread had me shaking my head.

You seem to be making things complicated for yourself.

"i don't know anyone else in her clique" - Uhm, get to know the people in her clique? You're a confident person, it should be easy.

'"hehe okay!", but i really don't know if thats a yes or just a nice way of saying "we'll see".' - Unless you guys speak some kind of abstract language, 'okay' means yes. Don't ask her again, don't even give her a chance to say no.

"when we do, i end up doing the bulk of the talking" - This just says 'clingy' to me. Give it a rest - talking at her when she doesn't want to talk isn't going to do you any favours.

And if you're set on just forgetting about this girl, you've got to remember that when you 'meet new people' it doesn't have to be girls you fancy. You can meet new female friends as well.
