even with the rent back agreement, you'd still have to move. sometimes life doesn't give us the chance to get ourselves all straightened out FIRST...there just isn't the time...so we have to suck it up, ACT AS IF, and get through it.
you are dealing with a divorce, no time to piddlefart around, you must be logical and sensible and shrewd. you have small children to look after, so you do what is in THEIR very best interests to secure a happy healthly life. i'm not saying that your feelings are not important, because they are....but when the ship is sinking, you have to get over the whole can't swim thing, put on your life jacket and jump.
