As painful as this experience is, its going to make you a stronger person, sounds silly right about now but its true. Provided you are honestly taking the steps needed to improve yourself, you will be better off for this experinece, with or without her.
I think its great you are using the coaching!
Its tough, but give her that space. GAL (get a life) and use your time productively. Continue using the coaching, continue working on the things you know you need to work on. Continue visiting this site, for me, its been an invaluable resource and source of comfort. There is a wealth of helpful info here
Time for talk is over, its time for action. Show how you are a better human being rather than merely talk about change. We did enough talk about change without enough follow through. As hard as it is, avoid chasing her, avoid emotionally draining dialog by bringing up the relationship when you see her. Do your best to put on a happy face and try to ensure every encounter you have with her is positive and friendly. Reestablish friendship, impossible to do if you are blubbering about relationship each time you see her, that will only push her farther away.
Take it day by day. I know its tough, its a massive adjustment, but it does get easier.
