I just read about your situation. I don't have the problems that you are dealing with but I don't think it matters when it comes to DB.
My wife doesn't speak to me at all. She seems happy that I have left her alone and stopped the pursuit. Like you I didn't do much in the way of housework and I also was distant with my kids to some degree. Since BD I have started doing more around the house. There were a lot things that needed to be fixed.
Hang in there. If your situation is anything like mine, its going to be a long road.
