Well, I'm afraid I can't be much help to you on this one. For the life of me, I cannot understand why someone like you would want to pursue reconciliation with someone who has had an A, DIVORCED YOU, calls you a liar and tells you to sleep with whomever you want, expects his XW to come up for the day and satisfy him on the drop of a hat, blames you for your lack of committment, tells you that you deserve better, doesn't have the COURAGE to change the mess he's in, ETC, ETC, ETC, ON and On and ON...
History aside, is this the kind of guy you would normally pursue an R with??
My LETTING GO advice to you would be to be DONE with this guy and find someone more stable and who WANTS TO BE WITH YOU, THE RIGHT WAY..
As I tell others in sitchs like this, "LIFE IS TOO SHORT". If I were you, I'd be OUT THERE DATING so fast, his head would spin.
You are DIVORCED, if for some reason, you still feel like you want this to be the guy that "loves" you, I'd start acting like you have fallen off the face of the earth, don't contact him outside issues with the kids, and let him FIND OUT what LIFE IS LIKE without you in it. Put some RESPECT back in your corner, by not going to spend time with an X who calls you a liar if you can't go to see him for a day..
You will be surprised at how even the cowardly of coward WAs, can muster up the resolve to win back their LBS if they are motivated to PURSUE so as NOT TO LOSE..
Right now, you're too accessible for someone who has been "Cut" so to speak.. Until that changes, I just don't see where the motivation for him to rethink what he's helped create in terms of the end of the M, is going to come from.
