If he needs something, then great. If not, just let him be. How
big of a habit did he have? Does
he have anything to help with the WD's? I never quite know what to say to people who are in relationships/engaged to people with habits. One side of me wants to help, the other side wants to yell run to you. You seem very committed by the wording of your post, so that's why I'm giving advice. Please, take care of yourself, too.
