I must admit Rose I tend to giving the benefit of the doubt especially where close family is concerned but when you wrote about your dad in tears in the nursing. home because of your younger sister not visiting him that’s when I saw the biggest of all red flags. You sound like you’ve given her the benefit of the doubt many times and she’s taken advantage of that. I’m sorry that she’s not been there for those close to her many important times and most recently for you.

I do however think it’s a good thing you’ve fully recognised the pattern- and that you do have support from your other sister. Who knows why she’s this way but she’s unlikely to change by the sounds of it.
