Ex has custody after taking me back to court when I moved from the state I was in to another to make a better life for the children.  Ex was already living in a different.  My soon to be 14 year old son wants to live with me and go to school instead of his dad.  States I can help more with school and he can get back on honor roll.  How can I go about this?  Ex will not hear of the change.  Have tried the nice way of talking to him.
