[Bilbo79]

I had a heart to heart talk with my W last night. I told her that we both had to make some decisions to make. that I could not continue to live in an open marriage. I already knew that she would ask to wait until after her brothers wedding mid jan.
I told her I would wait until then, but I had already been looking at apartments. we talked for a few more min, then she began to hyperventilate saying the thought of not coming home to me was too much to think about. so I comforted her, telling her it would be ok. I feel like such a push over.
