I dont know what to do when my dad is angry
So for a bit of background, I (16m) have had a lot of mental health issues in the past. I was a straight A student up until 8th grade, and switched to homeschooling in 9th. I've been to 6 Psych wards and one residential. I've been doing a lot better the past few months, but there's always room for improvement. My sister, (14f) is a star student and athlete. My parents are constantly gone for her Track meets, Basketball and Volleyball games, etc. She is on a travel volley ball team. My mother (40f) is a complete pushover, and is constantly stressed out with work. I do not want to involve her in this. My father, (47m) has bad anger issues, and refuses to get help or go to therapy for it. He has threatened to walk out on us several times because of varying issues.
There were a few issues that may be at play here, but i haven't been told so I'm not sure. First, i made myself lunch yesterday and was in a bit of a rush so i didn't clean it up fully after. The pan i used was cast iron, which i didn't know how to clean so my dad usually does it after i cook. (the pan is a family heirloom so i dont want to ruin it) He told me to clean it and how, so I did. My mom said he could be upset because I didnt clean the whole kitchen and just did my stuff.
The second reason it could be is, last night, i was taking my dog out and decided I wanted a drink. My Mom always keeps my sister stocked up on her energy drinks, and occasionally buys me a pack of soda. So i took one of hers, which she's told me is okay but i have to tell her. I would've, if it wasn't 2 am. i explained to her in the morning that i took one. she was mad.
So I woke up this morning and checked my computer, and the Ethernet wasn't working. So i went to the basement to check the cord, and it was cut. not just a clean cut either, the cord was stripped and so were the wires inside and they were all unwound.
This isnt the first time something like this has happened, when i was about 8-9 i had a ukelele me and my dad would play and sing to. He threw it out the window and smashed it on the concrete. When i was probably 11 he threw my phone out our upstairs window and smashed it (I had paid for it with birthday money, it was a cheap one.) He used to regularly lock himself in my room and throw things around, often breaking them. Last year, he took me to the psych ward because I wouldnt go to school due to bullying. He said he would just leave me there if they wouldnt take me so i made my situation seem much worse so they would. for most of these, i dont remember why he did it.
The worst part is, he always would come in my room after yelling or breaking my stuff to apologize. But i could always tell it was more for himself than me. I always forgave him, and the cycle would continue. Recently though, I've stopped forgiving him. Growing up, he would ground me or break my things but he would never do that to my sister. I don't think she's had her phone taken away since she got it. (They pay for her phone, but refuse to even let me have my old one because they dont want to pay the bill, despite me telling them I'll figure it out and that I can't get a job without a phone number.)
anyway, my dads been getting more and more angry when I dont forgive him. I dont think I have to. I just don't know what to do.
