Frog......another way of keeping the kids safe...or safer...is supervised visits....and, as I understand, there are various levels of that....
Perhaps, you need a more proactive legal counsel....and, even, perhaps someone who has had lots of experience in this area.....
One pattern that I have seen in regard to child visitation, and with my own children's father 9who was not an alcoholic)...is that they beat the drums about child visitation, in the beginning....and, then, when hey get the visitation, they don't even use it...and, taper off their visitiation with the children....
In my own case...I think his motivation was to "get back at me" and to keep the child support as low as possible (a stupid fantasy of his...lol)…..
Also, as an ego thing...to show the world what a fabulous guy and father he was.....(ha!)….
