My dad is cheating on my mom I recently found out that my dad is cheating on my mom,

and I’m the only person who knows about it. The situation is completely messed up, and it’s eating me alive because nobody else in my family has even the slightest clue. For context: my sister, my mom loves him deeply. His image in the entire family is “Ram-like.” Everyone—my mom, my grandma, my siblings, relatives—sees him as the most loyal, sorted, pure person. That’s how spotless his image is.

My personal opinion: he’s a simple, sorted guy, but he seems to have gotten caught up in the “new experience” excitement. Despite cheating, he still acts like he loves my mom and the whole family. His behavior at home feels completely normal—so normal that even I still struggle to digest the fact that he’s cheating. The only real change is that he leaves the house for 1–2 hours at night, saying he’s going for a night walk, but he’s constantly on the phone with “the other woman.” I’m the only one who knows who she is, and unfortunately, she’s someone connected to our family.

I can’t confront him directly. I can’t tell my mom; it would destroy her mentally. or she might end herself I can’t tell my grandma; she literally worships him.

But I also can’t sit back and watch this turn into something bigger. I’m almost certain this is the early stage of the affair. If anything is done now, maybe it can be stopped before it blows up and destroys everything. If I stay silent and my mom finds out later, the damage will be irreversible. I feel stuck between watching my family fall apart and blowing it up myself by telling someone. I don’t know what the right move is.

please help me, i can't focus on my neet prep my mind is completely fucked up
