I agree with AS. You have to be able to follow through and know in your heart that you are ok with him moving out when you state your boundries.
In my situation, I know that my H needs to give me total transparency, or move out. But I only said that when I knew that I would follow through on it. It's hard to think clearly when all the emotions are flowing. Really get quiet and think about what your goal is. Today, mine is to find some peace. I haven't closed the door on my M, but I can't live with him claiming to be faithful and walking around being secretive. Strangely, it was easier for me to just do my own thing knowing he was still with OW.
Trust me, you will know when you are done. I have no doubt that I need for these boundries to be met. None. Doesn't mean I'm not sad or that I still don't love him.
