Have you spoken to a lawyer? I was never served but he did file and the divorce would happen even if he did nothing as the judge would call it to trial. Once you have a lawyer, you can have it served there.
He doesn't seem to be on the ball with all this so maybe his mood swings are slowing everything down. Just keep treating him like you would the mailman. Just casual conversation, no relationship talk. Keep it together around him but it is ok to let it out when he isn't around.
