In desperete need of help.

I can see why you might be a little desperate. Confusing feelings always make things look a lot harder. Are you sure you're not in love with her? I think you just thought that was it, because you were afraid of losing her as a friend and you wanted to show her that you care about her. It's obvious that she has some issues herself. She has no faith in love, but wants to be loved very badly. What won't help her is faking feelings towards her. Neither one of you will get any happier by that. You shouldn't feel like her well-being is your sole responsibility and you're not allowed to be confused by feelings yourself. You shouldn't feel bad because you told her you loved her as a lover when you don't, because you didn't say it to make her feel bad.

What I think you should do, is explain everything to her. Tell her what you went through you when she said she'd quit fanpop forever. Tell her how bad so felt when you realised you're not in love with her and how afraid you were when you thought about dissappointing her. Tell her you want the best for her. Show her that she shouldn't have so less faith in love, because she is loved by you (as a friend) and that you are there for her to help her with her love life. Love between friends (especially at your age) can be so much longer-lasting and unconditionally than a fleeting passion between lovers... The fact that you felt the need to ask people for help with this shows that you care deeply for her and her well-being. So give her what you can give her, namely a great friendship, support and the feeling of being loved by a friend.

It will be up to her from that point. If she accepts this and is happy with what you can give her, she is more than worth your energy.
If she doesn't, her problems are deeper than what you can handle. Tell her that you'll be there for her when she changes her mind, but don't let her problems become yours. You were willing to make yourself completely vulnerable by telling exactly how you feel, and if she doesn't see or appreciate that, she's not worth your friendship.

Good luck!

oh dear this is tricky. go along with the whole love thing. if your only friends on fanpop then im sure this love will slowly fade, for her too. just try to hang in there until she feels like she just loves you as a friend. I hope this works!

(ps. r u a guy or a girl?)
