Although I haven’t experienced the loss of a partner for myself, I have had other instances where one partner consoled me about something related to another one. I’ve also heard from lots of other people about the support that they receive from those in their polycule, sometimes even from metamors (partners of your partners). Depending on how connected and in each other’s life the polycule is, I think it can be very helpful. I supported my partner get through his wife’s breast cancer treatment and I was more than happy to do that for him.

Thanks for your question and I hope that speaks to it.
