Really want to know if IABU as think I have lost all perspective. DGM died 3 years ago and a cremation was held a month later followed by a wake in her home town about 4 hours away. My cousin was executor of will (retired solicitor). It took several years to sort out the estate. My cousin emailed me then to say she was ill so could I sort out burial of the ashes. I liaised with the funeral directors and stonemason to get the family headstone lifted and engraved. I then arranged childcare via my mum for my youngest DD and confirmed a date with the funeral director nearly 4 weeks away. I then posted the date on family whatsapp saying any input in the burial was welcome. My DB came back within a few hours to leave the family chat and then sent me a separate private chat message calling me a first class c* and insulting my religion, and that I was burying his DGM without him.
WIBU? On reflection it obviously upset him deeply, and in order to avoid his reaction I would have been better to consult him before setting a date, but WIBU in not thinking it would be a big deal and the actual cremation shortly after she died was the more significant occasion?
