Why did my sister cut of contact with me and my mother?

My poor mother is 55 years old struggling with her health in a nursing home.

Out of all the useless ungrateful siblings I have I am the only one who is taking care of my mother. My mom is my everything my best friend.

My ungrateful sister continues to hold grudge and hate continues living in the past. Not only that but last time she called our mother my ungrateful sister yelled at my mother over the phone for th past 45 minutes complaining bringing up the past about how my step father sexualy assaulted her and bitch about how she was rub from her teenaged years watching after our younger siblings. And went on yelling how my mother took all of her biological father possessions.

My sister is selfish. I am currently working 3 jobs to pay my mother's medical bills. While my sister is swimming 🏊 in dollar bills she is wealthy as fuck and yet she denied to pay for my mother's medical bills.

She will die aline along with her wealth. Money can not buy happiness. I also saw my sister bring out our family business she's calls herself a Christian.

WTF It doesn't matter how my sister childhood was she is obligated to pay for our expenses and she must forgive us and move on.

One day my sister made the choice to cut me off and she doesn't acknowledge me. If I walk into her direction she switches to a different direction. Why is my sister so hateful?
