My aunt is a lot of people, and sometimes people's unintentional actions will be considered intentional here! When grandma was alive, my aunt always felt that grandma didn't take care of the children, but only took care of the little brother's children. How many sons does grandma have?
At that time, my aunt was young and energetic. If she doesn't feel well, she will call names at grandma's door. Therefore, there is a gap between my little brother and this aunt because of these! My aunt and her brother and sister don't know why, but they don't talk anymore. I broke up with my own mother because of some trivial matters. Later, the most painful thing for my mother was the day when my grandmother died.
Due to local customs, our place is still buried. When my grandmother was alive, my aunt gave her some old clothes, but she was worried that it would affect her later life (the dead locals can't bring other people's used clothes, which is taboo for future generations). My brothers and sisters told her that they didn't put it in, but she didn't believe it anyway. The point is that she can't find the old clothes she sent at that time. I don't know whether they are too old to throw away or why, on the day she was buried.
So up to today, my aunt has been isolated. Nobody wants to deal with her. What I want to tell you is that if other people besides your parents repeatedly challenge your bottom line, I support you to break up with them, and your life will not last long. Why are you working so hard to maintain this relationship? Sometimes it's not as good as a friend. Your tolerance may make the other person feel that you are easy to bully. Personal advice, for reference only!
