It is so so so so so tiring. And I think he's playing games, a bit. Perhaps out of fear, or uncertainty, or because he wants you to do something but isn't telling you what it is. Or because his abandon issues mean he's just not able to be in an adult relationship and do the work of repair. And it does seem like going dark and letting him experience what 'not being married' might feel like is the only thing you've not tried yet.
I hope you get your work done. I have a thing to do for tomorrow and I am not staying up late to do it tonight because I am exhausted and plan to be fast asleep in less an an hour if I can manage it.
