Impasse is a very accurate word, but at least we do have an open dialouge, so that helps. I have asked Him how he would feel about things if they were reversed, and as always, there is absolutely no way whatsoever that He can imagine shareing me with anyone. I am the mono one in this relationship and it has always been that way and He doesn't see that ever changing.
He won't move her in if I am not ok with it. I know this much. The problem is my not being ok with it. I so agree with appreciateing the moment we are living in. Perhaps he is bored and needs to be always planning ahead.
