Is it normal to stop caring about my parents cheating on each other?

I just turned 25 last week and it's been nothing but drama, watching them arguing growing up. One day my father wanted me (then 11) to say nothing about his affair. During my mid teens, my mom wanted me to also keep quiet about her cheating and even bought me some clothes, took me to eat ice-cream and gave me some money to buy my silence. Even if dad would've found out I was somewhat of an accomplice to mom, he would've been a hypocrite to get upset since he did the same in getting me involved in his affair too.

I stopped caring for the longest. It's one thing to cheat but why the need to involve your child into hiding your affair and lying to one parents. I ended up lying to both of them but it's worthless because they still found out about their cheatings. Their so called marriage really sucks till this day. This is like a trashy show by now. Is it normal to stop caring my now. If they want to continue destroying each other so what. Whatever.
