I'm sorry you're in pain. I recently came to the same conclusion and told xBF he needed to leave our house. I had a rough day or two but feel at peace with my decision to move on. And even so I'm sure I still have more moments of doubt and/or sadness in my future. I think how much time it takes to move to acceptance is different for everyone.
Keep posting to get your feelings out. I think it's better to go through the fire directly than spend a longer time skirting the edges being singed.
If you love somebody, set them free. http://tinyurl.com/2empx2g
