While all the DB principles are helpful for any marriage, I think that in your case your problems were so specific, you have to stay focused on that. If it were me, I would work on getting my sexual health back to a healthy place (with serious help from professionals), and once you have made some progress, I'd let your wife know, and see what she thinks.
It would be unwise to focus on all the regular DB practices if you're not addressing the very specific reason why your W left you. Many people come here having trouble understanding exactly why our respective spouses left us. In your case, you have a clear, specific reason.
Sorry if I'm repeating.
I hope you've made an appointment with a physician?
