wow, mommacat. I'm so sorry for what you're going through.
I'm kind of in the same boat so interested in seeing how things progress for you. Was (guess I still am) married to a cop and then late last summer he started growing distant and one day I came home and he had moved out. found an email between him and his therapist but he said it was just flirting. in a nutshell, here's my story: http://bit.ly/cK7MH3
It's great that your husband is being open though.. Wish mine had. Hang in there!! We're all here for you..
