Why was he the only one who cared?

During that “family meeting” my stepbrother was the only one who seemed to care. My “family” did not seem to care when I broke down from something personal… I walked away and came after me some moments later. After I broke down in tears, he came to comfort me, telling me that he needed me, which helped me feel a bit better.

He was talking to me as I packed my stuff and said kind things and was on my side.
