Hello Joey,
I think you already know that NC is a must..It’s ok to go on dates but try not to lose yourself..I beleive you need to find out what you did wrong and try not to do it again. I’m not the right person to give such advices but try to become better, change and wait. have patience and she may regret the break up. If you have common friends you an ask about what she’s doing and when you find a good oportunity and if you still want to be with her, you can try send her a text..Be calm and never get angry.. I hope you’re more lucky than me..
