I had a falling out with my nutbar father, didn't talk for years and at some point he told me he had cut me out of his will. We talk again now but I have no idea if I am in his will again. I don't ask because I don't care. Money from him always came with strings attached and I'd rather have nothing. Removing any concern over inheritance means I can base the relationship entirely in the present. Sorry, it's sort of hard to explain but it sort of makes me feel free from him.
My point is, being written out of a will isn't necessarily a bad thing. You can't put a price on happiness.
