I've a friend whom I consider as my best friend. I was with her at her lowest but she wasn't beside my side when I needed her the most. She ghosts me frequently and then reappears as if nothing happened. It disturbs me mentally. I have a toxic family environment as well. So this year both of us will be shifting to a new city for college. Initially I was of the opinion that both of us will stay together. But idk right now I have that feeling that I should stay alone instead and not with her. Right now my family is causing me trauma and later she'll give me mental stress. I have stayed with her at her home for more than a week and I felt that she's selfish. Yes she is a very good friend to me but I'm not sure if I want to move in with her and how will I say her no. She is the only friend I have.
