Backstory in brief: NC with my entire family of origin due to me bringing up abuse during childhood as my wonderful mother starting pulling the same crap with my own DC. Mother devastated as she did the best she could with me and was only 'joking' with DC. Entire family ditched me as I broke the 5th Commandment! Before complete NC there was a period of 6 months where my mother refused to speak to me as I had the insolence to tell her that I learnt my parenting from her after she told me my ASD son had nothing wrong with him, it was down to my shit parenting. I was barred from 3 family weddings due to this. At our next, and last, meeting she demanded to see my DC as she wasn't bothered about me anymore, just seeing them. I told her she had to resolve things with first so she stormed off. That was 4 years ago. 2 years ago DC1 now an adult, contacted her, and and my siblings, by letter and she did not respond. DC devastated as they were in her life for the first 16 years. I have felt suicidal at times due to the emotional fall out from this.
Anyway, my DC2 died at birth 16 years ago and is buried in a place that is now not local to either of us but my mother persists in tending her grave. I was furious for the first few years by the thought that my mother had ditched her living grandchildren who were upset but she was probably still getting mileage out of the grieving grandmother act. She never knew DD as she died at birth. She ruthlessly took over the funeral though. I sent a letter to a sibling (I'm not allowed to know where she lives) asking that they leave my child's grave alone but they have ignored my wishes.
Yesterday when we went down there, it was beautifully planted up again. No room for us to add anything. She's totally taken it over. I was quite calm about it and actually feel sorry for her. I can't explain it but I think this is the only way she can ease her conscience?
