I have to agree Sara. I think that your W's feelings for OM are clouding her judgement and its a distraction from the hurts she felt during the M. One good thing you have on your side is that you have made great strides in personal growth. You know what your faults are and you have worked your rear off making changes that are important to you. W will continue to see this new & improved GD and will not be able to ignore how you have grown and the man you have become. The seeds are there, just let them grow.
The statistics say that most rebound relationships do not last. Chances of this OM being around long term are slim. When this rebounder relationship ends she is going to be faced with all the disappoints of that R plus having to deal with the fall out of the M ending as well since it sounds like the OM is a band-aid of sorts for her hurts.
