Hi and welcome,
A move will not affect your children as much as remaining near to your ex will. Any person who would tell two children that if they move (like they have the power to make a decision like that) he will "cut them off" is doing more harm than good, it is emotional and verbal abuse. What kind of stability and security do they have now with a father who would threaten them in this way.You are the one who needs to decide what to do. Your children cannot refuse to go, there will be adjustment issues and, if you move I would suggest you find a therapist to help the children adjust to the move. In fact they would benefit from therapy now as a way to deal with the what they are experiencing due to their Dad's abusive behavior.
