I have not read the DB or DR books because I'm not sure which direction I'm taking. I've read 100's of threads in both the New Comers and the Infidelity sections, but haven't been able to identify because of my particular sitch (I think) is so different.
Sorry to tell you this but your sich is no different than 100000's I have read.
I suggest you start with a beginners mind and read DR and the links in my first post.
