Zues/Cadet - I agree completely in the way he should (not) interact with his W.
But unless I'm misreading, she took the kids and moved them an hour and a half away and is completely controlling and limiting custody and visitation. I don't know where he lives, but I'm pretty sure that's not legal. I can't recommend he sit idly for a few weeks without at least CONSULTING a lawyer to understand his rights and make sure he isn't LOSING any RIGHT NOW. Doesn't ean he has to file something yet - but at least a consultation, I think, is necessary.
