Sho, you might benefit by visiting my thread. Our situations seem to be similar in that my W was claiming OM was just a friend and I had no clue as to their true relationship other than knowing they were still in contact. I decided that I was no longer willing to remain in an open marriage and stated my boundary to W.
Do not file for D unless you are absolutely sure that's what you want. Once you 'threaten' it, you look like a fool if you take it back. Trust me- I did that several times before this past week, when I finally felt like I was 'there' and ready to follow through on it. Even then, I issued one last offer to W- work with me and give up all OM contact or we will begin D discussion and we will no longer be friends.
