My partner comes back tomorrow after the longest period away so far (3 days and 2 nights) with her new partner (which I believe makes him my or our metamour?) Anyway I have noticed in several posts on this forum that there is a certain etiquette about what partners should share with each other about their time with another. One may be comfortable, for example, with details of places they visited but not intimate details of their sexual encounters or relationship problems. Those are certainly things I would find uncomfortable hearing and would also not wish to be drawn into the role of helping sort out any emotional issues they have between them (having been placed in that situation previously). Is there any advice on these sort of boundaries?
