So me and my girlfriend have been going out for 6 months. She everything for me to make me happy. About two months ago I guess I wasn't giving here enough back. So she kept telling me to give her more on a couple Acasions. But don't get me wrong I showed I loved her and did the little things that matter. But I blew up and said its over. Now I'm trying to fix it and I made a huge mistake. She's still talking to me but she has another guy telling her my every move... Im trying to show her what an idiot I am. And I have but I just need some advice thank you

What the hell has the other guy to do with your relationship with her? Tell him to stop interfering.
Tell her all that you've learned from your separation and all that you're willing to do to make her happy. If she doesn't respond positively, you can only move on

I did... Now I stop talking to her trick and that blew up saying I'm not chasing her so I did chase her and that blew up to us not even together at all and she doesn't want to talk. Ahh I know what I have to do but I just can't let go of her she's so amazing

You have to 'let go of her.' She isn't a car or a cheeseburger or any possession. You force yourself to keep busy and learn from your mistakes (in this case, more than one!) for the next relationship. Maybe she will contact you some day, maybe she won't.

Relationships aren't a game with trick rules of chasing or ignoring. You speak from the heart, with honesty, and if dumped, you say 'I love you and wish I could work on what's wrong' and that's all. You respect the other person, and that includes letting them go.
