I hear you on that..... I don't think it could hurt to re-examine that agreement with an attorney----there might be more "loopholes" than you realize. If the ability to provide a living for your children is severely compromised----perhaps you could be allowed to move to a less impoverished location....for the sake of the children. I have heard of other cases where the ban on moving has been lifted under certain circumstances.
Just, please, don't let this become an excuse to dig deeper into a no good relationship......
