I can’t speak for all abusers, but mine has used child contact as a real weapon and been pretty nasty about it.
That’s why I took the advice to let a contact order go ahead, so the hours are set in stone and he has less chance to abuse me. With the no contact, it’s much more manageable for me. He’s mainly now twisting himself into a pretzel trying to affect me.
Every so often he will cause upset. But he has lost a whole lot of power compared to what he had before.
