Once they have custody, the abusive parents often start their own aggressive campaign with their children, to set the children against the protective parent. When the protective parent points that out as real and legitimate parental alienation, the courts often dismiss it, as they consider the behavior to be “paternal bonding”.
Leave it to abusers to find a way to project their own behaviors onto their victims, so that they can continue to get away with their abuse! It’s the old ‘turn everything upside down and inside out’ game, the crazy-making game that abusers specialize in. Not only are they actually alienating their kids from the protective parent, but they blame-shift onto the protective parent, in order to deliver a knock out blow and punish the protective parent for ever having crossed them. Slowly but surely, or sometimes before the protective parent even knows what has happened, the abuser has stripped the protective parent of both their legal rights and their emotional connection to their children.
