DEAR ABBY: My sister and I have always been close. She's married to a man I have always thought is domineering and arrogant. I also suspect that he's emotionally abusive from things she has confided over the years. These include days of the silent treatment, refusing to celebrate her birthday because he doesn't believe in it and discouraging her from taking a job she was interested in. He refuses to go to counseling and says whatever problems there are between them are her fault. I hold my tongue and try to tolerate him because she has chosen to stay with him.
He recently participated in a marathon and was connected to us and many others through social media so we could follow the entire two-day event from start to finish. After a day of constant "dinging" on my phone, I found his need for attention over the top and stopped following. My sister was very upset about it. She said she was embarrassed and hurt. When she asked why I stopped, I told her the truth.
