Hey ninajane - Welcome to this group. Before you throw in the towel, take a moment to read other people's "threads." We all backslide. DBing is damn difficut business, and we all take two steps forward and one back (sometimes two or three back!!).
My advice: - Don't EVER lose your PMA. - Visit this website often and read read read. - Keep this website and DR a secret if you can. - Shift the focus of your attention from your husband (or relationship with him) to you. This DBing stuff is not really about saving marriages as much as it is about saving people - specifically LBS's. Save yourself, and the chances of saving your marriage increase significantly.
There's more I could say, but start with this. Read and post here. This is a very supportive group. Hang in there, and don't quit!!
