I'm sorry, but don't count on being able to leave the area and certainly not the country with your children. Does your custody agreement say anything about having to stay in the area. If it does, and you leave with the children, you will be in more legal trouble than you want to deal with. Unfortunately, unless he totally loses interest in the children, you will be dealing with this man for at least 12 more years, if not longer. In my opinion, it would be best to figure out how to deal with him now rather than trying to escape him. If you moved away, what would stop him from following you?
