Why is my best friend against me moving to England and staying with my mother?

My mom invited me to visit her England. She usually doesn't answer the phone too much or barely returns our calls. She sends us postcards. She walked out on us when we were young and she doesn't seem to regret it. I was hurt that she didn't wanna talk to talk to us on Mother's Day. Anyways my best friend has tons of people to hang with but she rather jump off a cliff. Lol she crazy. I'm excited to see my mother. My dad knows I wanna visit her and I'm getting my plane ticket soon but he doesn't know that I wanna live there. My best friend through a harsh reality in my face and said, "I just can't seem to figure out something, why would you wanna stay with a woman that doesn't give a shit about you? She never calls, returns calls, doesn't seem to be interested in you guys, only thinking of herself and she just proved she doesn't want you. Why are you even considering living with her?"
That really offended me what she said and hurt, but deep down inside, she has a point. Is my best friend right?
Even my older brothers told me to not live with mom because she doesn't care and just let her go. My best friend didn't have to rub it in.
