what is your parents‘ relationship like in general

Tough, they fight a lot and my dad is very weird and emotionally unstable person. I have some personal problems with him, but it's aside from this whole cheating mess.

Are they involving you in their conflicts?

No, but I hear the arguments soo

Why did they fight about his infidelities in front of you

No idea. I was young, where were I supposed to be other than home? I remember a lot of fights

But I think taking a couple of moments to reflect on the consequences of any action right now (considering the past and current relationship dynamic) is not a bad thing.

You're right. I know that there are 2 possible outcomes, either they stay together but it'll be tough and my mom is gonna be always stressed about him cheating again. The other one is, they go through divorce but I can't even imagine how hard this would be. A lot of time, and money would go into it. Plus the financial aspect would be problem for my mom
