N/C
My mother is a weapons grade narcissist. I have the measure of her and so long as I stay alert we sort of rub along. She has some odd views about things, she can be completely tone deaf to the mood/emotion of other people (me) and doesn’t do boundaries very well.
My Dad has died. He had been unwell for some time and she absolutely controlled his every move. He was bullied by her and always took her part, no matter how unreasonable she was. But I loved him dearly.
My mother with nothing to do or control, is a Bad Thing. She has a part time job, and she also has active hobbies but she doesn’t really do close friendship.
So I need some help/tips on how to maintain boundaries without feeling guilty about her. For her part she thinks I’m a fool and an idiot, and would roll me over for my ex husband (who I’m divorcing for abuse) without breaking a sweat. She bought him Fathers Day presents, unprompted, for example, and didn’t see why I was 
despite him being a shit father who I’ve had to legally admonish for his attempted child alienation.
Sorry that became a rant. This week has been very hard and above everything I’m dealing with, it’s her that’s the most troublesome!
