I fear all the time that one day my son's mother is going to up and tell me she's moving with him out of state somewhere, and there's really nothing much that I can do about it except make her conform to the number of days I am entitled to have with him, most likely meaning he'd have to spend all summer with me and maybe a winter holiday. As a man your hands are tied. Our courts feel that simply having a vagina between your legs is grounds for being the better parent, no matter what your actions are.
