Help!

err.. Talk to her... I guess you've tried... Well, I guess use your action to show her you are real, don't EVER let her catch you looking at other girls :D praise her, do small things that show her you really care, for example leave love notes in her pencil case without her knowing, sent her flowers, spent quality time with her, oh yeah, share your poems with her ;) write some for her :) ...I hope those ideas help :) take care.

There is nothing you can do because the problem is not with you, it's with her. Sounds like she is really insecure and may have some inner feelings that she doesn't deserve anyone that truly cares about her. So she drives well meaning people away from her with her jealousy and pessimism. It's a form of self destructive behavior. Maybe someone should encourage her to recognize this problem and to seek therapy. I don't think this is just a slight problem.

just talk alot and become a good friend if she's beening having trouble she needs time to see that she can trust again she doesn't need therapy she needs people she can trust and you only get trust over a certain period of time and dont break a promise to her cause then your chances are as good as me actually being god

and as for the fear thing well just dont flirt with other girls... or dont show a great amount of like to other girls
