I am very sorry you and your daughter have had to deal with the heartache and bewilderment a person like this can leave in their wake. Sounds like he is a severe NPD bordering on a psychopath and had many people fooled. If you delve further you may find that he was more controlling over your daughter than you believe or she will readily admit. As long as she did what he wanted, all was well. He suffered a particularly severe narcissistic injury and has now devalued and discarded your daughter (the perpetrator). It is not productive to worry about him. He is doing what comes naturally to him (it has always protected his false self before) and he has no remorse about it. Of this you can be assured. Try to think of him as a robot who can demonstrate quite convincing human emotions but cannot actually feel those emotions. His life is like a stage production in which he has the lead role.
He has just moved on to different supporting players. As he said... it sucks for her. Not for him. Believe what he is telling you.
