I am a Teenager (f) and last night around 9:00-9:15 l heard my mom start saying "she" and since I'm the only other girl in the house I assume I'm in trouble until I hear her say " Oh my god is she coming here?" Then I hear my mom shut the door and my dad run down stairs while I hear a woman start screaming "she's fucking him she fucking him" and my heart drops I start hearing this woman yell "she's a fucking c word she's a s!ut" and now she's in our house yelling "bring her down here now" and my dad is saying " my children are here stop" but this woman continues. At this point I have been recording for a good 10 minutes and when I realize she's out of the house and my dad is outside with her I go knock on my moms door across the hall and I try to ask her what's going on but then all she said was " just let it go some things adults need to handle" and I kept asking and she wouldn’t tell me so I went to my room grabbed a towel and took a shower (I don't know why I did this I just did) when I got out I tried to ask my mom again but she wouldn't tell me so I went downstairs to talk to my dad and he wouldn't give me any information either so I went back to my room and texted my best friend saying 'some lady come to my house screaming and yelling' and as a joke my friend says "was it my mom? My parents are fighting and my mom just came home crying 30 minutes ago" and I text her "no way". Now I didn't see the woman but my brother did so I go ask him what he saw and it matched the description of my friends mom I text my friend right away and we both just don't know what to do. The I send the recording I have of th woman's voice and my friend says " thats my moms Voice” and I'm shocked I asked what car her mom had Because had seen the car from my window and it matches the exact description my parents have gone to bed at this point and it's around 10:15 l go upstairs and watch TikTok and just try to process what just happened ( I am one of those people that can't cry and it's very hard for me too idk why) the only thing is I stress eat, l'm never full ever, I'm always hungry, but I didn't have the urge to eat anything then at around 11 my friend texts me and tells me that her mom knows she's knows and her mom tells her the whole story. The original plan was say nothing to try and keep out friendship but my friend had slipped up when we were on FaceTime and her mom asked who she was calling and she said my name. But after her mom told her my friend told me and the at around 11:30 and I hear my dad downstairs I run down and I tell him I know and he just starts crying and hugging me while telling me he loves me I stayed up until around 2:30-3:00am. Listening to music and making bracelets Because I didn't know what else to do. Today I stayed home from school and have been just texting my best friend and I don't even know what to say or do I haven't seen my mom since last night because she went to work earlier this morning. Now I'm just sitting on my couch writing this does anyone have any advice? I don't feel bad but I should and I don't I don’t really feel anything just numb. I need advice

Update: I spoke to my dad found out it’s Been going on since December and I sobbed for first time in a long time I last time I cried like this is when I lost my grandmother in 2020 I’m so mad at my mom my parents have been together for 20 fucking years and my mom just goes and ruins it
