Imo the dad is worse than the mom (step mom) for cheating on his wife when she was taking care of his kid. Ngl if your husband cheated on you with someone AND had a kid with them you would feel like shit plus im sure she hasn't divorced him bc of her son...like if the fl's real mom had slapped her yall wouldn't say much but in the end slapping a kid is wrong. Idk if the real mother did something do the bother or not.
