Does it beat mean it loves?

Greetings to all! I want to share our family problem ... I don't know what to do, my sister was crying today. asked for help. Her husband had completely lost his head with jealousy. She never cheated on him and was not in his thoughts. And her husband knows it, and he tells us it. But as soon as he sees even the slightest sign of her communication with any man, he becomes "crazy". He screams, he doesn't remember himself, he breaks everything around. She screams that she wants all men. It's very hard for her. after an attack of aggression, the husband apologizes. He brings her any gifts and begs for forgiveness on his knees. But after a while, everything repeats again. Between the presences of aggression, her husband is a great man. Loves her and takes care of her. Since he beat her more than once in a fit of jealousy, something must be done ...
