When I first read your story, I had hoped that you would work things out and get back together. Sometimes couples take a break and reunite stronger than ever. She probably wants that.
If you want to get back together, call her and tell her and try to work it out.
If you don't want to get back together, I think that she needs closure. I'm not sure how to go about that or what role you can play in that. I think that she just needs time. She loved you enough to begin to build a life with you. It is painful to give up on that dream.
