Interested to hear opinions on this. Have been told that DM and DF now have an open marriage and identify as polyamorous. DM has a 'lover' she sees regularly and DF apparently has numerous other partners. This came about after DF was unfaithful which caused a lot of upset in the marriage and family.
As the adult child, AIBU to just say fine, but I don't really want to know the details? DM and DF seem to think this attitude is judgemental. I guess I don't really know where the line should be in this situation. Is it reasonable to expect us to meet and socialise with their other partners? To talk in depth about these other relationships? DM & DF still live together and to all intents and purposes to everyone else are happily (exclusively) married.
