My dss is 8 now, and for the last five years since I've been with dh there have been constant battles over access, and over dss's education/behaviour/emotional state. The ex has another son with her husband, who apparently is violent and abusive towards everyone in their household. I finally persuaded my dh last year to go to court, and we now have contact orders in place (which the ex frequently violates) and an order that dss should go to therapy, which he still isn't doing. A couple of days ago, dss was excluded from school for beating up and threatening other kids in his class. The ex called dh in and insisted that we take dss immediately because she was "worried about what my husband would do to him when he gets home." I love my dss and want to protect him, but would it be the right thing to do to go nuclear and file for full custody? DH and I have two daughters (2 and 4), and not much space in our house. And I'm worried that if we "took dss away from his mother" we'd be seen to be the baddies. Help!
