Alright, this day seems to be the turning point.
This morning i woke up to argueing, nothing new there. I went downstairs together with my sister, landing in a very tense situation.
Long story short, alot of things were said, and it ended up in my stepmom calling my sister names. After that my dad told her to get out of the house (her=stepmom) which she refused. My sister went to her room and was crying, i left to go to my sister to try to comfort her and we talked alot.
We ended up being afraid to go downstairs as there was no telling what my stepmom would do. Eventually we were both quite hungry so we just went for it. Dead silence. We ate semi-peacefully. After we prepared to clean the bathroom together, my stepmom came down in tears again. My dad followed not long after that, and my stepmom said "we'll i'll just leave then." My dad said he didn't want to go to her place for a couple of weeks (which they always do when my sis and me are at my mom's.) My stepmom then said they might as well end it here, to which my father disagreed, trying to work things out. My stepmom then proceeded to once again blame everything on either my dad or my sister, and turned to my sister to say: "(sister's name) is laughing her ass off inside right now" (she thinks it's my sisters' life mission to make the relationship fail.) We both ignored it and went upstairs.
She was about to leave and for all i care she drives into the grand canyons, but she's still here now. I'm very worried about my dad now, he feels in a position where he's bombarded by both his own children and his girlfriend, a horrendous position to be in. I want to show him i still care, but not while devil's incarnate is around him.
I talked alot with my sister so far, at the moment we're still hiding upstairs since we don't want to get caught in the artillery fire.
I just needed to vent this. Yes i know i am exceggarating and all.
I'm already thinking ahead of what to do now, i hope my stepmom dissapears so my dad, my sis, and me, can have a good life. We will show my dad we're not the cold terror children my stepmom thinks we are. (or rather, thinks my sister is) Perhaps we would even be able to have a genuine family laugh together, but i'm not going that far yet.
