I have a different experience to @Wisewomen
I had difficulty with my mother at the time I was breast feeding. I was committed to feeding and my mother made comments such as "I was not a cow". I continued with the feeding over medication and dont regret it as I think it helped my daughter grow stronger within herself.
My husband would ask my mother to stay for dinner if she visited, which she usually did, but she would make quiet little digs at me .. about the food or the table setting, or kids table manners.
Unfortunately I let my mother in. She is also quite a performer and very careful to indulge children in many ways. We were also grieving. I felt it important to allow grandmother relations as we did not have much other family and I wanted to be proud of my family. That we werent 2nd class citizens. Did I do the wrong thing. Maybe it could have worked out. I couldnt cut anybody out, but I found out that my mother really was not trustworthy and determined in the long haul to punish and undermine me. She "loved" me in her way, but it was very partial and not related to my existence or well-being.
I was very impressionable about our family's WWII stories. I now think they made more mileage of it than was honest given the circumstances my sibs and I endured.
It is true earlier generations have different contexts and often struggled with less equipment than mums of today. I wonder if that is the main cause of discord between so many mothers and their adult daughters
It seemed my mother was jealous of the "ease" she thought I was getting. She didnt take into account that I encouraged my husband and physically worked on our renovations, kept books, and never criticised his or her offerings. Whereas my mother was convinced she was a true lady and put down my father and me, and most other people, as not good enough, even when we gave everything to her and worked to a degree that ruined our health. Her style of self esteem cost my family a lot.
Not sure what to @Beatrix73 maybe you need a little separation with small meetings, so that you can be clearer what your real situation is.
Take care and be kind to yourself.
