You're becoming very strong. You're realizing that moving probably will not make him happy, or yourself, or your children for that matter. Running away rarely solves anything.
Would XH consider letting "HIS' daughter stay with you while he goes out and explores the world on his own? Let him move to the city....alone, if you aren't 100% sure that YOU want to. I think it's wise that you want to wait thru the holidays to make a decision as well.
