My bf is so double standard

Whole situation weird.. his daughter told him that he pays more attention to her then her mom bfs. & he told her I’m suppose to I’m your dad. He’s nothing to you don’t worry about him.. VERY WEIRD. Now wouldn’t she think I’m nobody to her? 😂😂 even though she asked me was I her step mom few times. WHOLE SITUATION NEEDS TL BE FIXED.
