I don't know how to feel about your parent when they're cheating on your other parent

I've known that my dad has been cheating on my mom, I still see him, doing face times with my mom when she's not around. Due to his job he has to stay away from us... I remember when he would sit in living room while my mom would be sitting somewhere else, he would keep scrolling on his phone while facetime would be going on side by side, they would just silently fucking adore their faces. That btch on phone won't speak. She knows that he is married, she knows about me too..

We are visiting him rn and there was a function at his workplace, workers families were invited too. My mom was chatting with another lady meanwhile this fucker was on call with that btch, showing her the gathering hall. I was so bewildered by how casually he was doing facetime infront of everyone, ofc he putted a thumb where that btch face was visible.

Once he was fucking doing it during family gathering, our extended family was sitting and this fucker was just sitting in front of a mirror and doing FaceTime. My little cousin (I feel) saw reflection and she curiously tried to go towards him, I covered up, distracting her. ...I mean fine u are fucking cheating, atleast try to be fucking discreet. I just wish I never get a husband like him.
