How should I say I want to start over with her?

Well this girl. Let just call her z for now. Me and z go back in time. I knew her for like 2 years. We was alway on and off ( we dated like I think 7 times). We use to alway fight and stuff. But by the end of the week. We would be back to our old ways. But we had a big fight like a month ago. And sadly by the end of the week. We still havnt said anything to each other. Finally she message me saying she don’t want no hard feeling. I guess I sorta forgave her. But man she said something on that day that was so out of line. That no one not even my family should say.you know it hurted me deep. Still it hurt it left a scar on my soul. But as most as I might hate it. I can’t picture my life without her. She was there when I was in hard times. And I was there for her when she was in hard time. I try to start over with her. I told her I was sorry and it was my false ect. And all she said was okay. So I just drop it at that but this time she came out and said something ( finally). I never thought love would be this painful and so much trouble. But even with all that. She is like the reason I smile. And even since we stop talking. It seem like the sun never raised back up. And I think it would be best if we started over. And rebuild our relationship back up. 2009 around april and may. Our relationship was at a all time high.I woke up and such a good mood almost everyday. Now I wake up and just think like man another day I have to live thru. Seriously I made my life plan around her. It was pass high school. Try to move with her. Go to college. Get a good job start my own family. And crap that fell to pieces. Now am at a dead end. How should I say that I want to start over. Or I want to have another relationship with you something around that? Like for real. I don’t really think I can have a real relationship with any other girls. Now that just how deep in love I am with her.
