My wife is fine with it. I don't go too crazy in my purchases. I buy by the group of fivers or sampler for the most part, a bundle here or there, onesies, twosies from the B&M occasionally. She'll take a sip or two on occasion, but she won't smoke a whole one. She even encourages me to "get a nice one" once in a while. Once when I went hog wild in a month, she just said, commented that I'd spent more than usual. That was it. She's a gem.
I don't smoke in the house, except maybe a few puffs by the lit fireplace. And in her car is definitely off limits (as long as I don't get caught).
