Am i wrong for saying fuck you and pushing my mother after she did the same thing to me

I'm 19M for context, my mother was asking me to do a thing that she already told me to do. While I was eating, I gave her a thumbs up and she said, "are you gonna do it?"And then I point to my cereal, and I give a thumbs up again because I was eating she thought I was giving her attitude. Even though I was trying to be funny. She then loudly says, again with this attitude.And I proclaim that i'm not giving you attitude, and then she proceeds to say fuck you, I say, fuck you back and she says, oh yeah.Fuck me, you fuck me and then gives like a knock to the back of my head.So that I get up and then I push her away.So she can't put her hands on me again because knowing her she would have not stopped. I then proceed to go over to pops(Her boyfriend not my bio dad) and explain the situation after me and him talk.He goes upstairs to talk to my mother and then he calls me and explains that she wants me out of the house 😑 he begins to ramble on about how we're both wrong and then says that if she had a gun, she probably would have shot my ass.That's what he said, I might be paraphrasing, but that's what he said 😮. She's like in her forties or fifties and is acting this immature.What part of the brain makes someone think "Oh, my child said fuck you to me and pushed me after I hit them I'm gonna shoot them 😜" paps are saying I should have never put my hands on her even though I pushed her so that she didn't put her hands on me again.I get the whole men should never put their hands on women.But does that mean women are allowed to constantly hit men and poke the bear? I'm not interested in apologizing to her at all i hate saying a woman is being emotional, but she was definitely being overly emotional Because how do you go from Oh, he's giving me attitude I'm gonna say fuck you?? Sorry if this doesn't really make sense or is written poorly this is my first time posting.I could definitely give more context to others and stuff she's done. Cause now that I'm looking back on my childhood. I really don't think she loved me in a way a parent should love a child, i guarantee you. She knows Jack all about me my interest, my hobby stuff like that. Again, sorry if my writing doesn't make sense this is my first time posting.
