Sounds like Mama definitely got it under control.
One of the lectures I heard gave the scenario of a party, hundreds of people, and said that if there was one batterer and one batteree they would manage to somehow find each other and hook up. Made me sad but also value the importance of getting to the root of the problem as you said so it doesn't repeat with someone else because unfortunately there is no end to the number of manipulative users out there.
Please keep us posted.
