My dear DM passed away five days ago. I’ve heard nothing from two of my sisters-in-law. We all live a long way a way from each other, but I checked old messages and for birthdays, deaths, new jobs - I’ve always been in touch with them individually. We all had a big family do a few weeks back and spent a few lovely days together. Feels so cold and unforgivable. While it makes no odds, her death was painful and somewhat unforeseen. I have no siblings due to bereavement. Lots of amazing friends though. AIBU to cut them out or to be so acutely hurt?
