I think people are being a bit emotional here.
If kids are living under my roof i should know where they are. You as the biological father may think only you and the mother are the only ones that need to be concerned but as my wife, she should respect me as the head of the household enough to know i need to be informed of where people im legally responsible for are located.
I dont see how its not reasonable to expect that when someone comes to pick up someone from your home to expect to know where they are going. If my sister comes to pick up my kids im going to ask where they going.
Nikka said your kids are now my kids, that isn't an amicable discussion nikka is saying he is deboing your kids and you must ask him permission to see them.
If your ok with that then
