"if she is denied hten i will be granted primary residential custodian. she cant say well i didnt win so im still going to be his residentail parent.. "
Yes she can. I have seen the courts deny requests for a parent to move with the child and because the parent did not move, custody did not change.
If they are not given permission from the courts to move the child, it is less disruptive for the child to remain with the parent they already live with, then move to the other parents.
I am not saying that will happen, but you have to understand, it can.
