Here's my input.
I have found that the divorce itself has been less traumatic on me than I originally thought it might. It may be because I am Standing, even post divorce. My ex-wife's contact with me has been very steady since the divorce. There is another man, but she has seemingly intentionally kept him away from me.
The advice I received from my counselor and a couple of other sources was to make sure she took care of the divorce itself, knowing that I did not want it, but not to make a fight out of it. MLC feelings are VERY strong, so what I've done is focused less on the divorce and more on understanding the process of MLC. It takes much more time to go through the process of MLC than it does to divorce.
I am not making light of divorce, and I have great Hope that my ex-wife and I will remarry one another. I continue to get consistent touch and goes from her and I believe she is continuing to process her way through MLC. However, it takes time......and you have no choice but to give them the time they need.
