My biological dad has never been a good dad he chose his absuive wife over his kids. I've asked him to try to video call his grandson he never does. He says hes too broke to send Christmas presents but post new tattoos on facebook. Im having my step father adopt me how do I tell my biological father and deal with the backlash from his parents/ siblings who I still visit. I just came back from seeing them 2 weeks ago out of state. My father acts on social media as if he is father/grandpa of the year. When he knows nothing that is going on and makes no attempt to.

I know I dont have to tell him but my stepdad thinks I should since legally it changes a lot.
