You've been given excellent advice. Easier said than done. She avoids being alone at any price. If this fellow calls you again hang up on him. He only wants to share his perverse view of things with you and you'll only get upset. If he persists get a restraining order put on him. She may tolerate his non sense but you don't have to. I'm not a parent. I can only guess how hard this is to watch. She'll come to her own conclusions and the way you described it, she's not in the dark. She'll come around.
