oh yes, the "I was never happy" syndrome, alive and well at the 2nd moth of separation, my H also blamed me for all his problems at that stage. Same goes for the fact that they don't seem like they ever want to come back, it's text book, this doesnt' mean he won't change his mind 4mths from now.
About his duties, don't ask, if he agrees that he'll take care of it let him take care of it and let him sweat it out, don't ask questions, even if kids won't be doing what you ideally wish they'd be doing or staying at, let it be, it is his job and he'll have to do it without hoping you'll ask, get po'd and take care of it.
