Wow, interesting question.
My first wife (also drinking buddy) and I parted friends but didn't contact each other after I moved back to Phoenix. I caught up with her last year and found out she's also in recovery, and doing very well. Yay!
Wife #2, mother of my children, and I aren't on the friendliest of terms. When I made my amends to her it didn't go well, her boyfriend was hiding inside the house, and a fight ensued. He has an assault charge against me, she has a restraining order. We're slowly getting to the point where we can communicate in a friendly manner, but for now it's good just to talk about parenting issues and scheduling our kids activities.
The hard part is remembering that we had a good friendship at one time. I guess I have to look at the bitterness between us now and remember that "this too shall pass".......
