I recently told one sister. About AM and WI and me.
She wasn't surprised at all. (She knew about EL.)
She said, probably second sentence after I told her about us three, "you must be loving this." I said, "well, I've found that I'm not always necessary..." and she stopped laughing about give minutes later.
What a total sense of peace and acceptance from her. What a total sense of being KNOWN. What an incredible feeling.
What did she want to know? How it came to be. And that we are doing well. Communication, sex life, a round robin of attention and listening - those were icing on the cake. Our creation story made sense, even with an outwardly straight wife, and that's what she needed to know.
And it really does feel amazing to have her know, have her understand me, and feel safe. She's the only family member to know about me and poly. I'm totally in the closet with family and all but a few really close friends. To feel this safe is an incredible feeling...
For what it's worth, WI has told one sister as well. It also went really well. Sometimes things work out fine, I guess. But we're nervous to tell anyone else...
