I'd have to echo OneArmed Bandit on this- let him make up his own mind. If its his choice, then fine and dandy. However if he is getting forced into it, then you might have reason for some quiet, yet firm words with his mum and partner.
Whatever you do, dont go off your rocker. This is Aunty Helens NZ now, and as a male concerned for his kids, you will get f^%$king nobbled if you cause a scene, and it will all be your fault(no matter whose fault it actually is)
Best of luck
