Social media

Is it harsh to block one of your friends on social media on another account. My other friend has also done the same before removing me from her account. I don't know maybe it's childish. I got tired of hearing about the same drama and knew I would be annoyed of the situation everytime she would tell me. She expects me to just listen and not give feed back but does that with me ~ she gives me feed back and although sometimes I don't like hearing it I listen. When I give feedback she gets defensive and upset. They say you somewhat become the people that you hang around and I feel myself changing n it doesn't involve my long time friend. I feel that we are not good friends to each other.
