My mother has dirty sex with other men and my dad enjoys watching her, i need advice?

nevermind how i found out, lets just say something weird was going down and i found out as children so often do. i recently found out the mum i always thought i knew turns out to be the biggest slut i can imagine and i have no love for my parents and never want to talk to them again. my mum enjoys meeting up with guys with massive dongs to have sex, often with my dad watching. found out she also likes to talk dirty and be treated like a slut by these men. how the hell am i meant to deal with all of this? to any of you who say i should be glad my parents are enjoying being filthy whores and pissing over the sanctity of marriage or that it has nothing to do with me, i recommend you stick your thumbs deep in your asses you sick liberal f**ks! the point is i don't and cant think of them as people i love and respect now, everytime i look at them i feel sick. to think they ever reprimanded me or told me what to do makes me so angry. i genuinely hate them now. where do i go from here and is it possible to ever get over my disgust? thinking of leaving home and never talking to them again.
