@Pleaseshutthefuckup - last issue first, when I 1st went nc, 4 years ago, I was really worried about inheritance. I don't have any of my own money, it's all in the house, disappeared in 10 years of being home, nor a way to make any (carer, kids with SEN etc), so it felt as if my one moment to get something that was just mine. I felt guilty, but at the same time, as if I was owed something I could benefit from iyswim. Meanwhile, DH said not to worry if it was about the inheritance, it's not worth the abuse, and over time I've made my peace with it, and got a small income coming in as well.
Meanwhile, my brother has confirmed that in the most recent will update everything was still equally shared, and our older cousin is executor and also scrupulously fair. Also, now she needs so much care, the chances are there won't be anything to care about anyway, so all moot.
I've done really well intellectualising this whole thing, learnt all the jargon (1st discovered the concept of narcissistic mothers 15 years ago), and know theoretically what I need to do. Which is not see her.
However, in the lead up to this trip I've been getting the dreams/ nightmares, headaches, snarly etc etc. I've been wishing for a whole different set of memories. However long you've been doing the sane thing, however good you are at creating a life that works for you, occasionally it's as if the past 25 years of work didn't happened and you just want it all to be alright. I finally cracked this morning, talking to my MIL, which was great, because I got a big hug, and she understood how difficult it must feel. I'm not sure she understands never doing to final duty meeting, but she's gracious enough to just be supportive, listen, and provide solace.
I feel stronger, both for writing it all down here, and of course post-blub.
