Sometimes we do these self destructive things because of deeper issues. I did something similar but on a phone chat thing. I pretty much fell apart. My husband eventually caught me, but somehow we worked it out. My husband is a good man but a little cold, so like you, I went in search of the comfort and companionship. After several heart to hearts we found out communication was not our strong point, and we worked on it. Maybe you could talk to your wife no holds barred. Tell her what you need sexually as well as emotionally. Maybe you can find a happy medium. I wish you the best.
