One thing you need to know is that unless your spouse can prove that he contributed to the house he may have no claim to it (since it was a gift from your dad). In which case you don't need to move. You may be surprised at what he may wind up paying you in child support (if you have kids) and alimony (depending on how long you have been married). Years before my divorce I figured out I could make it on my own (would have had to cut back on some things, really did I need to pay for cable TV.)
