Hi Flower01
Yes, he’d love it wouldn’t he, to get back inside your home, make his presence known, start up all his old abuses again, right in with the family again.
Go with your instincts, he’s an enemy, and doesn’t belong inside your home. It does seem likely that he would have pressured the children to ask for this. either that or they simply don’t realise the implications for you all.
warmest wishes
