Should I confront my father?

I don’t ask questions I don’t want answers to.

I saw my dad comment relentlessly on some woman’s Facebook, pretty smile, looking good etc etc with a bunch of emojis.

Honestly they could be just friends, colleagues maybe he even thinks of her as a daughter but my gut doesn’t shut up.

Should I just text him, who is “abc” ?

What if his fb account is hacked, i low key know it is not but benefit of doubt. And he is not an idiot to publicly expose himself by commenting this BS.

What do I do? There is no turning back once I ask him. And if I don’t ask him, the restlessness is killing me.

Doesn’t end there, I will know if he lies. So idk what to do. Fml. I don’t think I can ignore it, should I?
