Sorry WMLC...they do seem to get stuck on their course of leaving
I know for me, MC was a complete waste and the same thing happened to us XH did not want to work on M, He had A partner and was going to leave as soon as he could convince me and the therapist that he was right in his choice to leave.
And all of that looked good for him at the time, he was free, in a new R,much younger OW, He had a good job, he looked good/lost weight and was happy to get a new start---
Fast forward 10 years-- He has had much trouble with OW--they got D and not sure but maybe back together
He lost his family, of origin kids, and close friends
he lost his high paying career and worked as a clerk in a store, he became addicted to prescription drugs and alcohol and so did ow
His freedom became his nightmare
Truthfully in my opinion, it does not matter which way things turn
You can let her go, do your life, be cordial and kind or no contact she will do what is best for her
If she is in MLC, you will notice her choices getting poorer, you may see a decline in her decisions or drugs/alcohol/spending also her parenting skills decline-I would watch the kids and see whats going on in that department
either way, you can continue to watch from a distance
If she wants to come back- you can leave a door open if that is what you decide
You dont have to make any choices today
You dont have to help the D, if she wants it, she will file
but I would definitely know your financial and legal rights because some MLCers will want to get as much as they can with no thought about you or the kids.
