Bel9izzy,
Did he ever cheat on you? I wouldn't say I'm a sex addict but being a guy with a high sex drive I don't know what line you cross to become an "addict". Sorry to hear what you are going through. How do you begin? I guess it depends on if you have accepted or if you still think their is a chance to reconsile. Also would you want to? There is a lot of support here. I'm no expert but I would say if you have accepted it then next step is to focus on you and don't look to far in the future. Just concentrate on taking care of you. You will get through it and you are not alone.
