Dallas' 4 Eva
Superstar
maybe there were red flags but maybe those red flags were from the ex which is why she decided to bring her new boyfriend this time, while that's just as possible, there's a vested interest in only imagining scenarios that places blame on the mother.
If the ex was a threat to her safety due to past indiscretions their drop off point wouldn't be face to face in the first place it is very easy to get that court ordered with or without a historyof violence either way. See my real world example as reference. You don't have to do a custody exchange face to face.
