The thing to work to work on is your own desperate need to get back together. Reconciling from a place of desperate need is unlikely to go well. It will serve you best to focus on yourself and seek to control that which you can control. You are worrying desperately about something (her) that you can't control.
We all do this in the early stages, and I do understand, but the sooner you can get going on your own journey - separate to your W as she is taking her own jouney - the better.
