I am the OP, and I thank those of you who offered support to me, and my children. For the record: my husband and I divorced a month ago. I asked him REPEATEDLY what the status of his relationship was with his roommate, and he looked me right in the eye every time and denied they were involved. Two weeks after the divorce was granted in court, he told the kids the truth. FML only accepts stories that start with "today...." so yes, I fudged that bit a little. They have been together for two years. We were still in marriage counseling when they started up. And no, I didn't know. Seriously. I didn't, When someone you have known and loved for 20 years tell you something, you tend to believe it. Until you find out your whole life was a lie, that is.
