I've just read your thread for the first time. That's maybe why my response is a bit different from others.
You are starting to sound like a WAS. Are you o.k. with that? Really? Truly?
You've gone through so much and worked so hard for so long ... maybe you really are done. But are you really? Do you feel it and know it?
If you think or feel maybe not, then perhaps you may want to tell X that you'll go to counselling if she still wishes to set it up. You don't do anything but show up and listen (at least initially). It's her ballgame from there. Worst case scenario may be a better co-parenting relationship. That's a pretty good one.
Sounds like maybe there's still some room for you to make an active choice as to whether this is a speedbump or milestone.
She walked away but certainly isn't done with you. You may want to be sure that you don't end up in that position as well. But maybe you are sure now, I can't tell.
