AITA?

My husband and I got into an argument. He kept yelling and our kids were right there. My 6 year old was covering my 3 month old's ears and telling him to stop yelling. I told him to be quiet and he yelled for me to not ever tell him what to do and started telling me to shut the fuck up. (All in front of our 3 kids). My 6 year old actually whispered to me if we could call the police on daddy. He kept going off and eventually said that he was done and we were separating. I said ok. He looked at our 6 year old and starts telling him that mommy is a bad partner, that we're going to separate because daddy is so unhappy and that we're need to not live together anymore. I pack my and the kids stuff up and start to head out the door to go to my parents. He stops me and says that he changes his mind and that i can no longer take the kids with me. I said I'm not leaving them. He gets out his phone and starts recording and says that he's going to call the police and have me arrested for taking them against his wishes. My 3 year old is crying saying he doesn't want to stay with daddy and my husband grabs his arm and tries to pull him away from me. I kept saying to let him go and he blocked my 6 year old from leaving the hall way. Eventually they both broke away and got to me to which we left immediately. I told him id sign the divorce papers no problem.

Well it's been a few days now and he's backed tracked on all of it saying that he's going to start therapy and get on an SSRI and that he didn't mean any of it and that I'm now the one choosing to break up our family and keep him away from his kids. He wants to move us all to a new state and basically "start over". I told him if he won't continue with the divorce like he said after bringing our children into it, forcing me out and then ultimately saying it's literally all my fault, then I WILL be the bad guy and do it myself. Am I wrong here for not wanting to try marriage counseling and work it out? He saying that I'm destroying our family but I don't want anything to do with him now. He's trying to offer gifts, compliments, saying he'll buy me anything I could want. But I honestly feel like he has definitely traumatized our children after that and it's not the only incident to have occurred like this. He's doing his best to make me feel like a pos for choosing to go through with the divorce and saying that I should sign up for therapy and get put on an antidepressant and get checked for BPD.... Am i being unreasonable??
