UPDATE:::wrong or not?

I live with my boyfriend and we have a almost 6 month old baby boy. He is divorced and has 6 teenagers daughters and sons. I have met all his kids and they all nice with me but except the oldest daughter. She still do not want to meet me. Of course all of them has meet my baby and they love him. His ex wife and his oldest daughter want to see my son but told him that no. I don't know why the ex wife is insterested in my son when I don't know her and haven't met her. So is not fair that his oldest daughter want see my son when she do not want to meet me. My boyfriend's daughters had got mad with the oldest that to grow up and to meet me. His kids love me and I don't have problems with them, we get well along together. Do you think that I did wrong for her not to see my baby when she do not want to meet me? I was thinking that the more I let him take my baby with the ex house then the more his daughter wouldn't want to meet me...just saying don't know. What can you guys advices? My boyfriend got super mad at me for not letting him to take my baby for her daughter to see him. He has been talking to her but she still do not want to meet me and she is 24, I think.
UPDATE: now my boyfriend want me to tell his daughter sorry but told him until he tell me sorry for threatening me bad and talk me back so loud infront of his family. Also told him that how when she do not want to meet me and said that he will talk with her. He ignored my son and want nothing from my baby just because of that. Told him that next time if he do that then I will pack his thing a to leave. A father should never threats baby like that. After work I went to pick up my son and saw him that he had my baby in his arms. Maybe he got scared and do not want to leave us.
