That's all fair, but I can't shake the feeling from reading this that he's trying to cut out her family completely. In an ideal world, they'd be a great source to turn to in those struggles of raising 3 kids. Now, in reality, he may be a POS, her family may be POSes, or some combination of both, but either way, there's something more in play here. It doesn't go to court if it's just a simple case of him moving on.
