Hey, I am a 16 yo girl, and I wanna know if it's possible for an older brother to be indifferent towards his sister in this kind of situation.

So, the thing is that tbh I am a very young, and also a very lonely girl, I've been very lonely for the last two years, my parents have been too busy to pay attention to me, and I'm not really friends with anyone, because I live alone and have no family here with me, and as I told you I'm very lonely, so I went back to my home town, and because I had no one to live with, my older brother took me in, and all I wanted was a family, love and a family, tbh I don't care a lot about money, I know I'm very young, so I am willing to do whatever it takes to have a family, but my brother has been too indifferent or maybe even too cold, towards me, he doesn't even talk to me, and it hurts a lot, he took me in, but his attitude makes me want to leave, I've been nothing but good to him, what's his attitude supposed to mean? I've always been good with him, but he's always so cold, and I seriously wanna leave, I think he even likes me, but he's always so cold, what does it mean? I want a family, and he's my only family left, but I don't think I can stay with him, I'm not sure if I'm going to be able to stay with him, what does it mean for him to be so indifferent to me?
