You know what is so great about this place? It is the undeniable truth that while we are all as different as night and day, from all walks of life, from all over the country, etc., we are exactly the same when it comes to this damn addiction.
Man, I cannot count how many of those moments I had when my wife would walk in the room and I was thinking "oh shit" as I tried to cover up the dip in my mouth. Like in your case, my wife would have this look of disgust on her face asking me, "WHAT is in your mouth???" The last "bust" was a couple of days before I found KTC. I used to find comfort in being holed up in my home office that is located above the master - it is an area that typically only I enter with the exception of my 5-year-old daughter (who would come up and ask me about the "candy smell"). It was my comfort zone where I could dip without getting busted. She'd call me and I could spit out the dip and chew on a bunch of gum and floss real quick before running downstairs. However, I started getting lazy. I started leaving disposable coffee cups filled with spit in them in the trash can (strategically placed so they wouldn't spill over). One day she comes upstairs. The smell hit her and she KNEW what it was. She jumped my ass 6 ways to Sunday and didn't talk to me for 4 days. I was literally weeks into my quit on KTC before she finally started believing me that I was really quit and not just lying again.
My point is, stick with your quit and she'll learn to trust you again. Now my wife is VERY proud of me. While she didn't understand the addiction (she, too, never used nicotine) she knew it was something I struggled with for many many years. Hell, she even keeps up with my days now and has bought me a special present for my 100th day. SOOOOO, stick with it...the trust will return.
My point in that long story -- we've all been there. Shout if you need anything, you are doing a fantastic job. I quit with YOU today.
