Your relationship with your wife should be more important than anything else on earth. If she's like mine and has no addictions, make sure she reads the stuff on this site. She will have NO clue on what's about to happen, even though she will be right there at ground zero.
Sit her down, tell her you need her undivided attention. About 20 minutes with no distractions. Let her know that she means the world to you, she is the most important thing in you life. But there's a problem. The nic bitch. The nic bitch has sneaked in and taken control. It owns you. You are an addict. And the last thing you need is for someone else to come between you two.
You are quitting to make sure she stays number one and that you also take your health back . And, unfortunately, it will involve her. You are going to be a bitch yourself. You'll be irrational, tired, cranky, a whole different person. The last thing you want is for your relationship to become collateral damage.
Show her this website, especially the sections on what nic does to you, what quitting does to you, and what the spouse needs to know. Tell her you have to quit, but since it involves her, you won't start until she read it all, is on your side and says go.
Then quit. Odaat. Lean on her as well as the quit group. Don't let the group become more important than her. Thank her. Remind her this is for her too. You will not only have a good partner in you quit, but your life partnership will also strengthen.
Celebrate your 100 day by taking her out to eat. Let her know that you can afford this fancy place because you're using the money you didn't spend dipping. Make a big deal out of her and your 100.
Congrats. You will still have to struggle to stay quit, but the hardest part is done. And most importantly, your wife is now more important than the nic bitch again. And she knows it. There is nothing better than a wife who knows, not just that she's loved, but that she means more than anything else.
