If your H wants a divorce, HE should be the one to file. Let him do the work. It's what he wants, not you, right?
Agreeing with issues he has with you isn't the same as caving in to the dissolution of your M when you believe in it. Validate his feelings, but don't get pushed around, either.
This is my suggestion, so take it w/ a grain of salt, but I think it's time for LRT. If you haven't read DR (or DB), do it now and start detachment. If I'd had the sense to do that when my W hit me w/ the news, I'd probably be in a different situation right now.
You cannot change his mind right now, so don't try. Become unavailable and let him do the work if he wants to end the R.
Very wise advise. Read it, live it.
Everything will be counter intuitive, so it is very important to listen to the wise advise here.
Pursuing him WILL DRIVE HIM AWAY. Pursuing includes reasoning. The sooner you set him free, the better the odds he will change his mind and pursue YOU. When he pursues you, DO NOT STOP DOING WHAT IS WORKING. Let him continue to chase.
It is very important for you to work on YOU right now and make positive changes.
