yeah, sorry. I got paranoid. I've been accused of being judgmental by said family member and I don't want to come across that way at all.
I really am at a loss of how to handle this situation, other than distancing myself from them. One person of the couple continues to tell my spouse and I details of his/her affairs, details of their arrangements, details of the arrangements our mutual acquaintances who also are open etc. All of which we find to be totally unnecessary, particularly because we aren't apart of that world. I find it offensive and off putting.
It's just so difficult to watch your family member and their spouse engage in emotional and sexual affairs, even though consensual. Not to mention be apart of their "lie" to other family members who aren't aware of their arrangement.
