Jim, It sounds like you're making progress with each step. I wonder why your wife wouldn't want to file jointly to save money? Why would that be worth a fight? Your wife is little greedy in some of her requests! It seems you're doing the right think by letting her go and not trying to reconcile at this point, but it's just too bad your wife doesn't want to put in the hard work to get her act together, save the marriage, and make her life better. You have no control over that. You seem to be doing what's fair financially and cooperating well. All of your actions sound appropriate.
