Fathers an endless circle of lies.

2 weeks ago during vacation my dad, my sister and I had a fight.
Fights aren’t unusual, so you may understand that we’re tired of fights.
That’s how it went:

The evening went fine, my dad dropped my boyfriend of at the station and then proceeded to his own dinner reunion with his friends.
It was around 2am(I think?) he was back home.
I hadn’t heard or noticed him coming home.
According to my sister she did hear him take out some wine bottles to drink , before she dozed off back to sleep.
My dad went then upstairs and started yelling at me.
“You have no sense of responsabilities, where is your sister?!”
“I have no idea.” I replied honestly, I had been playing games with my friends since it was vacation anyways.
“Maybe she’s downstairs sleeping.”
I knew she was as much as a pc addict as me so it wouldn’t have surprised me if that’s what really happened.
But my dad didn’t like that answer and went on yelling, so what do most people do in those situations?
Ignore it, right.
Then he proceeded to go upstairs, where he ‘surprinsingly’ found my sister.
He yelled a bit at her for no surten reason.
And then went back upstairs to yell at me for being up late.
Apparently I had no reason for staying up late while it was vacation (ofc makes total sense).
Since he wasn’t really planning on stopping his ranting of screaming any time soon about how my grades were horrible, how he didn’t deserve to have children like that, I proceeded to the exit of my room.
But no, he blocked the exit so I couldn’t leave.
That’s when I pushed him aside since I was already getting pretty damn pissed about hearing his scenes again.
I HAD to get space.
Another accusation, ‘you punched me!’.
Needless to say, I really got the urge to punch him, it was around that time that my mind went crazy I suppose.
Thus I went down and grabbed a knife in case he wasn’t planning on leaving me alone, with his door blocking (hey I told you I went crazy).
Upstairs, he never had to plan to leave me alone.
That’s when I threatened him with my knife.
“Leave me alone.”
But he didn’t seem to care; no he even stepped foreward, he wasn’t retarted, he knew I couldn’t harm him or he could call the police on him.
I freaked out and stabbed the wall instead, needless to say the knife broke in two (sorry people knives aren’t so strong as you guys might think).
“You stabbed me, you stabbed me!”
He looked like a lying tomato flapping its arms around.
I started crying (I went nuts remember?), threw a pot with a dead flower out of my window, with the result of it smashing in thousands of pieces.
I ran downstairs to find the door surprisingly open with my sister outside.
“I knew you would come, let’s go.”
Apparently her argue with our dad didn’t go well either.
So we went, bear foot, to my mom.
My dad took his car to track us, but that only caused more drama.
Eventually my sister and I took different paths.
Worried about my sister I told myself to keep walking (it was freezing outside around -5°c).
Once I got home I would tell my mom and she could help me look for her.
At the door, I rang the bell and got welcomed by my mom hugging me, it appeared my sister was earlier than me.
She didn’t allow my dad to pick us back up and decided to take care of us for awhile.
Even though he tried calling my mom, they got into a fight aswell.
She could tell he was drunk and didn’t like that idea.
We went to sleep around 5am.
Not really a good start for my mom’s new job not to mention that the next morning her car broke down.

Now it has been 2 weeks, my mom still has her job.
And my dad is still calling, he asks me to come over this weekend.
And to be honest, I know he’s my dad, and that he probably cares, but I don’t want the fights anymore, it’s not the first time it has been like that for years.
My boyfriend sugested changing the parenting system to his, the mom’s the one who takes the children full time and the dad passes by ones in awhile to go somewhere, and during summer vacation he sleeps over for 2 weeks.

So tell me what should I do?
