What's my next move, do I move on?

Basically me and my ex girlfriend have been broken up for about 5-6 weeks, she was the one who did the dumping. I won't talk about why we did because we sorted our reasons out. Anyway I want her back so bad but at the moment she's saying she just wants to be in her own like not have to worry about a relationship... she keeps telling me that's what she wants but saying she thinks about it all the time in wether she's made the right decision. Through out our relationship I have always been there for her, yes I made a few mistakes like moaning at stupid things but hey I'm young, mistakes are meant to be made. Yet she was always having a go at me, I never left her I always stayed and treated her like a queen, always out up with her **** yet as soon as I make a mistake she leaves.

I tried no contact so many times but I keep breaking it after a week and telling her I want her back. I want her more than anything, but all she is thinking of is the mistake, she won't consider everything good I did for her and how I could have walked out so many times. Has anyone got any advice on maybe influencing her in a way like to make her think twice about if leaving me was the right descision? Anything I can do that she will notice and make her think twice? Also we are both 18 and I kinda get upset when I find out she's going to clubs because she's single I don't want her to be hit on all the time:( any advice would really be appreciated, thanks
