Gitterdun, Fordtruckman! Dude, I was in your shoes. I chewed and dipped for 20 years, and hid it some of that time. Or at least I tried. The women in our lives are smarter than we think, but they stick around even though we lie to them. For that, your wife deserves a reward. Quit, and stay that way.
Here's the problem you're gonna have that you need to be aware of: in the next couple months, your temper is going to be all over the place. You're rage will at times come from nowhere with no warning. You MUST be prepared for that, so you don't take it out on your family and friends. They did nothing to deserve it. I didn't let my wife in on my quit until I was 50 or 60 days in. It got a lot easier after that because she realized that I didn't hate her and that I wasn't just being a prick for no reason. That's a tough one in your situation. I can't tell you how to handle it exactly, but I know you've got to be aware of it.
I'm gonna drop you a PM. Reply with anything you may need.
