AITA for not wanting to host Thanksgiving?

A few years ago my DH told his sister he was unable to attend one of her parties, because he had to watch our children, so I could visit my dying mother in the hospital. Her response was to the effect of, “I wish her mother would hurry up and die already because her prolonged death is ruining my social calendar.”

After getting wind of this comment I refused to host Thanksgiving for their family last year, which SIL told my husband we were “required” to do. She later confronted me at her home when picking up my children. She swore at me, refused to let me leave the house by holding the front door closed, and then followed me out the back door threatening me and swearing at me, with child in hand. There have also been issues with her making disparaging comments to me and my children over the years.

My DH was just told we are required to host Thanksgiving this year…. And he is demanding that I do it. He says it would be unfair to exclude his sister and unfair to him because he wants his family over. Do I suck it up and host for the sake of my DH or stand my ground?
