Honestly, unless he wants to wait until the PFA order expires in April, AND hope that she doesn't successfully get it renewed, he's really got no shot at this without the services of an attorney. I know that's an expensive answer that he doesn't want to hear, but the court at some point already made a ruling that the order was warranted, and even the BEST attorneys struggle to get courts to re-evaluate such orders...a non-attorney realistically doesn't have much of a shot.
