while also praising himself for having enough control not to go farther and actually choke me

What the fuck? Many partners get angry and lose self control, yet most manage not to strangle their partners as a general thing. Is this praiseworthy? Seriously? One would think not attempting to kill one's partner is a basic requirement for a relationship, not something to be lauded.

If he hasn't been violent with you, he's threatened violence many times and has been violent with others. Let the facts speak for themselves. You should have been gone from his life well before this. Hopefully this is the wake up call you require, though it's a most unpleasant way to have the fact demonstrated.
