Welcome guy. This is a smaller forum - quality not quantity!!
No, I don't have a success story to share. In fact your story sounds much like mine, especially the work and social references. I too will be divorced shortly.
I wish I could encourage you but 2500 miles is a long way. On the other hand time and distance may work in your favor. What are your custody arrangements - when do you see your kids? That at least is a bridge. Any chance you moving to FL? Is her parents supportive of you?
Other than that continue to improve as you have been doing. One word of advice: don't get too focused on your part of the stitch. It is so easy to take all the blame - I know I did and that drove me crazy. A R takes two - she had a part in it too.
