As you know, I have a lot of experience with the reluctant resolver. I can tell you that you are closer to a resolution than I am 3 years in. I don't think you want this to be dragging out years from now. His desire to delay is about him, and him alone.
I think you know he wants to find a way to get you to hold off without actually committing to anything. Returners quite often point to the OW as making demands for the divorce that they were facially trying to comply with. I suspect there is a lot of that in my case. He feels safe that I won't file so he tries to look like he is being aggressive.
I think your idea to go forward without him is a good one. I would have done so long ago if there weren't compelling financial and visitation issues involved in my situation. While anything can happen, I expect to have to be the one to file and push it through when my S graduates.
