Your soon to be ex husband sounds illogical. When he forces you to listen to his illogical thoughts (picking up yet another box)... if he says I want to work this out, and a few sentences later says you weren't there for him blah blah blah... take the line of control. It's OK to say he's right that you weren't there ( you werent and thats ok, you dont want or need to be), but remind him your reasons for that is because you have nothing good to give him. His choices are be happy he's free, be miserable he's free or be quiet and deal with it. He still has choices.
