My abusive sister-in-law

My sister-in-law is a she-devil. She uses female bullying to make my life misterable whenever I have the misfortune to see her with my brother. She listens to all my brother's phone conversations. I asked my brother a couple of days ago if I could have a private phone conversation with him, without his wife present. He got angry and said, "If [his wife] is not there, then neither am I." I said she treats me cruelly. Now I don't have a brother anymore, either. And my brother and I were very close. I can't get these two people off my mind. I am so depressed I can't even play my guitar and sing today. I am lying in bed listening to beautiful piano playing, which is very nice. I blame my brother for bringing this she-devil into our family, and he is completely fooled by her. He thinks she is absolutely wonderful. But she gossips and says terrible, untrue things about me and my sister to other people. She relates to people who have married into the family, but not to the actual blood family members. She buttered up my late mother, who thought she was wonderful! My late father hated the sister-in-law. He was very good at seeing through phonies, but my mother was adamant that the sister-in-law was the most angelic person on earth. The sister-in-law brought my mother flowers every time she and my brother came to town, and even though she is not religious and my mother was, she went to church with my mother just to be on her good side.

I can't get these two people out of my mind. I am so depressed. I don't like it that my brother won't have a private conversation with me.

I also realize that my being depressed is making the sister-in-law feel very gratified. So I am playing right into her hands.

How do I absolutely forget about both of them and write them out of my life? Any suggestions, anyone?

Do you have a good relationship with your sister, as you both seem to be getting the same treatment? Can you find support in her?

When there is a level of toxic behavior like this it is best to stay away from that toxic person or, sadly, your brother. I'm sorry this is happening.
