WIBTAH for cutting my mom off when I move in with my dad after my dog passed?

Me and my dad were close when I was younger, He eventually had to focus on work in Georgia when I was around 8 years old. I used to love my mom but ever since my parents split she’s been a total ass to me. And I mean yell at me for everything, She always ignores me, and she absolutely HATES my best friend. [I’l be calling my friend Ally for privacy]. Ally has been my friend since the start of freshmen year and she’s honestly one of my only friends. Ally has been through every mentally abusive thing my mother has done. My mother is absolutely toxic. She blames me for EVERYTHING that happens in her life and comes to me about her boy problems [She’s like 50 and has 3 boyfriends, and i’m only 16]

Recently my dog has passes away. [R.I.P] He has been with us for 11 years, When he was dying we were all with him, but what does my mom do? Start taking pictures of our dying dog.

That honestly really upset me because you decide to post and tell everyone that our dog is passing instead of being there in the moment? Later that day i called Ally for comfort of what happened, i was telling her what happened and it made me upset that my dog passed and that it made me even MORE upset my mom was taking photos and basically telling everyone we know. Even random strangers on the internet.

My mom over heard our conversation and got mad at me and started shouting at me about how I’m not allowed to tell anyone about personal family business and if I wanted to talk to someone, It had to be one of my brothers.

A few days ago we went to go get our nails done by a nail tech [I wasn’t very interested on getting them done but i was forced for her ego] What is the first thing she tells the tech? Our dog dying. I was absolutely taken aback because what do you mean, you tell an ABSOLUTE stranger our dog passed and started showing the photos?

For years now she’s been always been doing such hypocritical behavior, from blaming me for the dogs death, yelling at me for everything I do, being unsupportive of me and my passion and constantly ignoring me and saying that “Oh it’s because i’ve been through alot” I don’t understand how that has anything to do with you not being a good parent and always emotionally/mentally abusing me?

May this year, I’m moving back in with my father jn Georgia. And I absolutely yearn for it to come closer.

I love my dad and left my mom because she was just this way. WIBTH for cutting her off?
