How should i tell family about elopement

So our original plan was to do a big wedding next year and that got postponed to 2022 due to covid and also stress due to my fiancé getting covid and still dealing with health problems because of it. He and I were originally going to do an elopement and then have a wedding for family and friends. However, about a month ago my fiancé’s father’s health has started to decline and we think he has the beginnings of dementia. So we’re not even sure how much time my fiancé has left to make memories with him before he declines further. So my fiancé and I decided to just do the elopement this year and include our parents and my brother for the ceremony and pictures. I still haven’t told my parents because we still had to work out with the b&b folks offering the elopement package if including them was even possible. But I am still feeling pretty guilty because I did promise some of my extend family that they would be included in the wedding in 2022 but now that’s not happening. We do plan to do two live streams so our extended families can see. I really don’t want to hurt anyone’s feelings though so I’m looking for advice on how to tell them all this week. Has anyone else been in a similar situation?
