AITJ for saying i rather live with my mom then my other mom during a game?

I’m 16M last week I was playing Would You Rather with my mami (31F), my Mom(32F), my uncle (40M), his wife (38F), and my cousin.

My uncle loves messy questions and my moms have been like on edge with eachother for like a week pior and still are I dont know what happened i came home and they just mad at eachother and have not really made up.

And he asked me if my mom and Mami broke up, who I’d rather stay with. I just answered my mom without really thinking about it because it was supposed to be a game and i was just playing the game.My Mami got really mad and my mom was trying to calm her down when she said, You’re not even his real mom and a whole bunch of other stuff and my mom got mad.

She’s technically not she is my stepmom, but she’s been in my life basically since I was born and help my mom when she didn't have to cause they met as teens.

Now they’ve not really talk to eachother. I never meant to hurt them at all and I think something wrong her cause she never acts like that yeah she freaks out and stuff but not like that cause she actually got mad at me to and I feel like a jerk and still feel like one cause I don't knkw whag happenebing between them but they aren't talking at all.

My Mami basically doing the slient treamemtment not responding to anyone but me and if she want tk ask my mom something she tells me and then I have to tell her.

And I feel like jerk cause I said that and my Mami is even more mad but j wasnt thinking.

Sorry for the poor grammer and spelling I am still working on English better, and haven't gotten it all correct yet.

TLDR I was playing Would You Rather with my family and my uncle asked who I’d rather stay with if my mom and Mami broke up. I answered my mom without really thinking because it was just a game, but my Mami got really mad. Now they aren’t really talking, and my Mami is using me to communicate with my mom. I feel like a jerk because I never meant to hurt them.
