Just adding my $0.02 - but I would go out on a limb here and say
he is wrong. No, and I mean exactly zero - adult relationship is one-sided, or even close to that.
Further - there is no such thing as being "a little abusive!" He is minimizing his harmfulness for whatever reason. While acts of harm do vary in degree of harmfulness, responsibility in the first place is binary. He either owns what he did or doesn't. A hallmark of abusive men is that it's never their fault. He's subtly imposing the responsibility entirely on you by saying he let it go on way too long. Seriously? It was somehow your job to figure out what he didn't like before his failure to self-manage resulted in him acting out? Not buying it. He is responsible for his behavior and the same for you.
Nobody makes us do anything unless they have coercive power over us!
Yeah I know I'm being cranky, so take all this with that in mind. I'm coming from a place of feeling compassion for what I see as you taking on way more than your share of responsibility for the outcome. I have done this before and it hurt like hell for me. That makes me want to speak out in the hope that you are aware that you have the option of rejecting what he has to say - on the grounds that it's bullshit.
