How can i prove to my ex girlfriend?

(back ground)

This girl and I met a year ago at school. And last school year we dated twice. but she broke up with me because she liked someone else. And sort of treated me as the ';rebound';, or ';second priority';. But for some reason i still liked her and we would always come back to each other. (girls name - Krystal)



(Now, recent)

A several months ago i gave her a love letter. It told her that how i loved her and stuff. But as months passed i seemed to had moved on. And dated this new girl. We broke up, but i still had feelings for the new girl. (New girls name - Emma)



And at my commuinty highschool football game i hung out with Krystal my old ex, who i had big feelings for too. We flirted a lot and i started to like her alot. So i had to choose krystal or emma. But then a week later i went out with Emma again and broke up with her 6 days later. ( i know, a waste of time)



And now Krystal is mad at me cuz i didnt choose her and i told her that i liked her a lot and now i want to go out with her. But we both know that i can;t just fall back on her right after i broke up with Emma. And now im in a stressful position. And Emma is not too fond of me and Krystal is having second thoughts. But i want to prove to her that i like her alot and made a mistake and want to be with her.How can i prove to my ex girlfriend?
I think you should do them both a favour and keep away from them until you've grown up a bit- well -alot.You sound like your 12 or 13.How can i prove to my ex girlfriend?
Trust me, if there are two things girls love, it's feeling loved and drama (though they'll never admit that second one). Give some big heart-filled speech about how you were wrong you made a mistake and you still love her and she'll swoon. I've done this twice... with the same girl. It's easy as hell
get the hell away from the girl. dangerous and a waste of your time. the Emma chick got screwed. Tell her that and maybe you have a chance with her, but run far away from the original chick. And stop writing love letters.
Your a dude and making us look bad, quit playing the fence and just choose one. Be a man and tell the other you made your choice. If it doesn't work then at least you did the responsible thing.
She just a h*e
Sounds to me like you're treating Emma the same way that Krystal treated you. I think that you need to grow up a little bit and stick up for yourself. If you like Emma and she's gracious enought to take you back again, then you should get with her and make it stick. Girls like Krystal are sleezy b!tche$ and you will eventually learn that they aren't worth the time or the energy that it takes to make a relationship work.
yea, you messed up. though the best way to fix it is to claim the ';i was lost at the time'; You can throw the '; i like you alot, like alot and well, i was so destroyed when we broke up, the idea of dating you and breaking up scared me.'; tell her that you realized it was just your guard you put up after her. Your best option is to claim you were stupid, and you realized that She was your best choice and you were a fool for picking the wrong one. your gonna have to open up to her, Girl hate it when you dont ';pick them'; your gonna have to really work on her. Your going to have to open up and let her know whats really going on.
