Re: I want my H to move out, but I can't afford the rent all by myself!
Hmm...I understand the dilemma. I really think, though, that regardless of which of you moves out, that person shouldn't have to pay half the expenses. The money being used to pay half the expenses in that house is less money for that person to find another place to live.
If neither of you can really afford to keep the current place entirely on your own, I would see if finding a roommate would be an option. If not, then I would talk to the landlord, explain the situation, and find out if there's any way you can be let out of your lease early. The landlord might take pity on you and let you out without penalty, given the circumstances, but even if not, you can always take a month or so to save up to pay the penalties, and then you would both be free to find new places that you can each afford on your own.
Plus, it might be better to start fresh in a new place, anyway. That way you wouldn't be surrounded by memories of the two of you together.
