Why has she stopped talking to me?

She always calls me a moron or fu**ing stupid. Sometimes she asks me to be checked for autism. I think she bullies me. But i'm fine.
She has just stopped talking to me. I asked her why and she said becoz i don't listen to her. I asked her why via text message but deleted it later coz i didn't want her to be annoyed. She didn't read my message for two days then yesterday she told me "i saw ur message but didn't read it so that i didn't have to talk to u."
Why has she stopped talking to me?
