I think I would be a lousy metamour too.
I am not quite sure about this subject, but talking about it today,...My previous interactions indicate that I treat people the same under this title, that I would anywhere else in life.
If I find the person interesting, and want to befriend them, I will,..and it happens rather naturally. It`s fantastic when it does happen that way.
If I don`t, It`s 'Hello" and a courteous: 'Hi, How are you?" when I see them, that is it.
I am thinking this is more important in poly relationships that don`t subscribe to a Primary/Secondary title ?
When I think about my husband and his dating, I can`t say I feel a need to make sure I know everyone he dates.
Good subject to ponder, anyhow.
