I am going to put another spin on this one. Iv Been in a relationship with a person who was constantly overruling my decision in front of the kids.
Everytime he did it I felt humiliated, like he was being "passive aggressive." And that he put me at the level of the kids when he did this. Not only undermining everything I said, or decision I made when it came to them, but also making me feel like my partner thought I was stupid and incapeable of making decisions. Therefore he unknowingly made me feel like crap.
When I confronted him he got extremely defensive and wouldn't talk about it, that's how I knew he wanted all control and what I said didn't matter. It hurt me very badly.
This also caused the children to "tell on me" with every decision I made and therefore they could get it overruled by him. That too was demeaning, and humiliating that I an adult was unable to make any decisions regarding them On My own.
The fact he didn't listen when I tried to tell him how it made me feel put a wedge between us. He refused to hear my side, and it made me feel like what I said didn't matter. The worst though was being overruled in front of the children, it was just horrible. It caused me to almost hate my partner, and the day Ieft I didn't feel sad because I wasn't sad to loose a relationship where I had no voice.
He wanted all control, and I was merely a thing who's feelings didn't matter, no matter if he felt that way or not that's how he made me feel.
The day I left I didn't shed a tear, 7 years I walked out because of it, the only emotion I could muster up was relief. He sat there crying as I walked by, but I felt no guilt because I had warned him, and he just didn't listen.
I know your angry, and that's a normal reaction when it feels like your being attacked. I don't know the whole story so and that's why I told you mine. Maybe you can relate to it a little. Perhaps he chose words like "abuse" that you didn't agree with. Maybe he just meant to say it hurt him. And sometimes that can feel like abuse if it's done over and over. But it's only abuse if people are aware they are hurting someone, and they continue the action that hurts the other person.
It sounds like he did try and tell you in his own way that he was being hurt, wether you meant to or not, perhaps a redo of the conversation after you both cool off might help.
Good luck. :)
