Maggie, I have the same kind of arrangement, except we sleep together, well sometimes she sleeps in the other room when I have asthma and I snore. We are still married though. I call us partners but I have heard my wife call me her friend. Most of the people she knows and works with all know me. I worked with them also. I don't work there anymore. She also does not consider us lesbians and I don't either. We are not intimate, not even with the kiss anymore. We basically live together because we have been together for a long time, since High School and we really don't want to date anyone and economically it works well with us. If we were to split up, we could not afford the lifestyle we have enjoyed and worked a long time for. So far it has worked. My eyes have been wondering but that is all, just wondering.
