You are incapable of judging what other people think about you because they are in charge of what they think and you have to ask/they have to tell you; guessing on your end not allowed!

But I think you're doing wonderfully recognizing that she has the issue and has been "harboring" all that stuff against you; dumping it on you like your mother dumped on you in the middle of the night is HER issue, not yours. You're doing well getting away from her.

But I wouldn't sever all relationships until the relationship proves to be a problem for you? You cannot avoid getting hurt or surprised; we can't "control" other people and how they respond and what their issues are; we can only be comfortable with ourselves, in ourselves so that their drama doesn't impact us. Keep working on your mother and your marriage and things that mess up your ability to care for yourself but I wouldn't dump everyone willy nilly until I was sure they weren't being helpful? How are you going to know how you impact others until they tell you and not all they have to say is always going to be complementary?
