I Ended a Friendship

I ended a 5 year friendship after she called me an evil person after making a joke about her brother. Its been three months since I talked t her now and I just accidentally logged into my other friends phone from that day we went over her house. She had texted my other friend saying that her mother can't stand the sight of me. it hurts since I met all of her family have even spent thanksgiving with them and she has meant mine. The only reason I made a joke about her brother was because her brother had threatened to beat me up and kept calling me cave women and she didn't stand up for me.
