I found out that my mother is cheating on my father who is your typical beta bucks providing for a cheating woman for 17 years now. She doesn't even have a job. And is always demanding something from my father. Currently she wants my father to buy her a new tooth which costs around 1000$.

They are constantly screaming and arguing in the house. I litteraly can't stand them, they stress me out so much. Right now my father is drunk as fuck, it's 11PM (I have to wake up at 6:30AM for school), mother is also kind of drunk and won't stop screaming at my father. Calling him a pig, fat man, not a real man, etc. I told my mom to fuck off if she continues to scream like that at night and that she is free to leave the house if she continues. Now she is acting like she can't imagine what is happening to her, her own son is talking to her like that. But I honestly can't stand her knowing that she is such a manipulative bitch, cheating on my father while using all her resources.

Should I tell my dad that she is cheating on him so that she can gtfo from the house. I will miss her and I deeply love her but still, I know I'll have to accept reality. Also I'll be able to bring girls to my place because she won't be at home 24/7 which is a huge plus for me.
