I guess it all boils down to your true reason for needing this stuff to be dealt with. This is exaclty what you ask us when we're in the same dilemma!
If you have accepted your H's sitch as his sitch and can legitimately reach a state of mind of moving forward with your life then by all means ask him to comply wth the agreement or whatever you want done about it. If however there is some level of pursuit involved then think before you act. And as you well know its so hard to not have some level of pursuit or own agenda in the mix!
