Omg I'm sorry to hear that. It's really terrible when such behavior comes from family members. I'm happy to know you're independent from her now. I too don't associate with my mom that much now since I've been on my own for more than a decade. Too toxic for me. I mean, yes I love her but it's best that we're apart.
It is possible of course that our parents' behavior are partly from their own parents. They were probably raised that way too and so are acting like such when they became our parents. This is why I'm very happy we have the internet nowadays. We can easily find a way to be better people as opposed to the older generation who don't take advantage of the online world.
