Have your Mother caught your father micro cheating

Well my mom did 6-8 years ago and it was the most shitiest thing to happen the first night she found out about it they was screaming at 1-2 am therefore bothering me and scared the shit out of me, my mom was screaming about how his entertaining other women despite the fact that he have a family, the second night was the same, shouting but she started throwing things she came to my room crying at that time i didn't really understand anything since it all happened at night but i did hear my mom talking about a certain woman that i know of amd then thats when it click me that my dad cheated on my mom then a few weeks after that they started acting normal again as if nothing ever happend which is weird you know she should've left his ass back then.

So here i am now wondering if any of yall experienced this and how did it affect you?
