The thing is that the last time he tried this (in an attempt to get 50/50 custody) he ended up with the current order, which is two hours of supervised visits per week. Want to know how many of those he has used in the last two years or so? THREE. Yep, that's it. But he went to parenting classes so that should be enough right?
I have about 7,000 reasons why he shouldn't have unsupervised access to the kids. I don't anticipate having any trouble whatsoever convincing the mediator the same, but it sure does ruffle our calm world to have to go thru this crap at his whim.
