What should I do in this situation?

I think you have to make up your mind what you want. If you dont want her, then as things stand it's over, and you need do nothing. If on the other hand you've realised that despite the problems you are far happier with her than without her, then you had better make contact with her. When she asked if she'd blown it, and could she have another chance, you said she couldn't have another chance. She's already a girl who doesn't make the first move, so after being told she cant have another chance, she is not going to keep trying to contact you. Expecting her to beg and plead is ridiculous. If you cant love her the way she is, it's a good thing it has ended, but if you can love her regardless of the communication problems the two of you seem to have, then you will need to try to get her back. By the way, the odd, emotionally detached style you have in telling this story makes me think there are problems on your side, too. I think, if you want her back, you should have a long, honest talk about the way you deal with each other, and find a way of communicating more honestly, without all the gameplaying you describe (you broke up with her, told her she had no more chances and could not put it right, then sat about feeling miserable and wondering why she wasn't chasing after you) perhaps with the help of a good relationship counsellor. This is supposing she would actually consider getting back with you.
