I sincerely wish you success in the struggle with your addiction.
Please hold on to the fact that you have two little kids, and you and their Mom are the two most important people in their lives. Be available physically, emotionally, and financially for your kids even if your wife decides to leave you. Know that, if you remain in their lives, you will always have their love no matter what.
Best wishes.
