I think you misinterpreted what I posted, i.e., "Please stop expecting him to do things". I meant don't expect him to put out the trash, have sex, do the dishes, pick up the kids, all the normal chores that he would have done prior to crisis. You can't rely on him for anything because he'll say he will do it and then won't, or he'll conveniently forget about it or will do it half @ss, etc.
As for being his emotional porter sorting out his relationship w/his children and being his life secretary...oh h@ll no! He's a big boy and can figure out his taxes, immigration, driver's license and insurance paperwork. He fired you as a wife, lover and companion.
I wouldn't do it all for him...again he's a big boy and you are not his mother. When he asks if you did something, just say, "h, I didn't have time to do it or I've been busy and didn't get around to do it". Smile and walk away.
Time for this man child to grow up and learn to do things for himself.
