Here is my situation. My ex and I were married 29 yrs when we divorced. It has been many, many years. We have 4 children and 3 grandchildren, the oldest grandchild graduates from high school this month.
My ex and I were not at all friendly the first couple of years following divorce, which was unwanted on my part. Long story is there was OW, who he still is with but they have never married, although live together.
Put of necessity, we have had to communicate because of our children, so over time our conversations became more "friendly." OUr oldest son was diagnosed with a mental illness a few years ago and we have had to work together to help him.
At present, we get a long quite well., but couple weeks ago we did have a minor conflict and I didn't hear from him till last week.
He was scheduled to go OOt to visit our daughter and our grandson, and He stopped by unexpectedly, the day before he was to leave, saying he didn't want to go out of town with me possibly being mad at him!!! That was a first!! At the same time, He also suggested that we just send our granddaughter one check and card for graduation and just sign it from Grandma and Grandpa--that he would send me his portion. He and I plus our son have gone out to dinner a few times, at his invitation.
I guess you would call this a couple of examples of reconnection. Not sure what is up with the OW since she did not go with him to see daughter. I also thought he and her would be sending granddaughter a joint gift--she has known our granddaughter since she was quite young.
I don't know if this is what you were wanting, but if I can answer anything specific, I would be glad to.
