I just read this at NLQ this morning; that's really scary that he was doing that. Scary and wierd; I would have guessed that he (or any abuser) would refuse to teach you.
But then he wouldn't have had a built-in sparring partner, would he?
I'm so very glad you got away!

He didn't see himself as an abuser so I think there was a disconnect there, a denial, that enabled him to teach me self-defense and spar with me.

I'm glad I left, too. :)
