I suggest that you take a few days and then make the decision as to whether you want to push forward on the divorce or not. Why take a few days? Because you are emotional right now and the only way that you are going to make a good decision is when you are calmer and more settled.
If you truly don't want the divorce, then don't proceed, just table it for now. If he truly wants it, he'll get his arse in gear and see a lawyer and proceed from there.
Some of these kooks play games. My xh played and played and I was beating my head up against a wall about a divorce, etc. When I tabled it w/my lawyer and advise him that he was to cease responding to my xh's crazy lawyer's lettters, that's when he finally got his arse in gear and filed himself.
Sometimes, it better to do absolutely nothing and let things ride out. You've gone above and beyond attempting to do the right thing w/your kooky h. Now it is time for him to either sh*t or get off the pot.
Step back and allow this situation to play out for a while. Go dark, do not respond to any more of his calls/texts about the paperwork. You've tried numerous times to get things done. Now, it's his turn to step up to the plate.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
