Feeling left out.. Being poly but not having multiple partners
I'm having a bit of an issue. My husband, K, and I are poly and he has a steady girlfriend, S. We are a part of a large group of friends that are very much intermingled with people who all have multiple partners. (S is also dating J and M, M is married to P, P is also dating S and R, etc. lots of intermingling).
I find myself feeling left out in this group because I am only with my husband, K. I do consider myself poly and am supportive of it with my husband. I have been on a lot of dates but have not met anyone that I want to have a steady relationship with, for various reasons.
So, I am very happy with my husband, but starting to feel lonely, especially during the times he is with his girlfriend and I am home alone.
Has anyone else been in this type of situation? Where your primary partner and all your friends have multiple relationship and you only have your one primary? How do/did you deal with these feelings of loneliness and inadequacy?
