I was an overbearing jerk to her -- how do I fix this?

im sorry to hear a thing like that, in fact i am a girl myself. ive been in that situation in both points of view. it might take time for her to come around. shes stuck in the world of ONLY him. she should come around in school, and be more open to you, to have a convo. in the halls or in a cl. dont be to forward. or during school you can wait on her, if she doesnt talk to you in a week say a simple hi(: but she might be testing you to see if you would still fall for her, so shes ignoring you. sometimes girls cant handle a situation like this and then they stop talking to the other guys. try not to text,call,e-mail and what ever else there is that you do, for a wile. you could even hang with other girls try to make her jelious, but show that you care that you still want to talk to her. i hate to say, maybe shes not for you, maybe she was put into your life to show you a side of someone else. i hope this helps in any ways, i wish you luck:D <3
