My DM and DF separated and divorced roughly 20 years ago. My DF had an affair with my DMs best friend and it broke her. My DF ghosted my DB and only kept in touch with me because I have his two GCs - about 15 years ago he messaged me to say he was getting engaged to the BF, I got angry and to cut a long story short apart from cards and vouchers as Christmas and Birthdays for the kids he cut contact encouraged by his narcissist wife whose was very happy that she didn't have to share. Last year he caught Covid and died, our situation was never resolved - the SM didn't tell us he was ill until he was on life support so we couldn't resolve anything or speak to him again - she 'couldn't work out how to use his phone'. A year on and the Will has been actioned, there was a couple of thousand for each of my DCs but myself and my DB have been written out and all of his money goes to his step children.
And now for the problem - I have to tell my DM about the Will. She knows he died, we all went to his funeral, she knows he stopped contacting us, she doesn't know about all the nastiness through the years, she doesn't know about the letters the SM sent over the years to me and my DCs telling me what a poor excuse for a daughter I am. All the nastiness that is still continuing, she's sent letters to my DCs badmouthing me. I'm literally just getting over the last letter - I'm fine during the day but at night I lay awake talking to myself, having conversations about what I could say to my DF if I could. I'm exhausted by it all. I know I need to tell my DM about the Will, I've kept all the bad stuff from her to protect her over the years, she's made a good life for herself after being treated so badly but when I tell her our DF left us nothing she will be devastated and feel terrible. I don't want her to feel like I do about it all. How do I tell her - does anyone have any good ideas on ways to broach the subject?
