Mono, I certainly don't mean to imply that her concerns about poly are illegitimate by saying that she is jealous. She has recently described what she's going through using that word, and I can certainly empathize with her! I have been experiencing jealously since they began dating. It is an uncomfortable and awkward feeling.
I do agree that the meeting itself will probably be low on the jealousy and high on the awkward, though. And I do think that I will refrain from being physical with him while we're in her presence for now.
I wonder if, as things settle, we'll both get comfy seeing each other being physical with him...?
