There are so many more resources for you on the "Mid-life Crisis" board. I think you will get a lot more help there. Even if she isn't in MLC, there is a lot of good information there about "standing" for you marriage without being a doormat and such, cake-eating, etc. It is a long journey, and a lot of patiences is needed. I have been doing this for almost 4 years. I have not always been good at DBing, I have made huge mistakes, but I have changed myself in the process which is the most important thing here. I have had huge slip ups, but I am human.
Tell us more about your situation. We are here to help!
