A great post. I'm fortunate that my wife tolerates my pipe (and cigar) smoking. No, I don't smoke in the house. I've never been told not to, but all the same, somehow, I understand that I shouldn't. We really don't want the house to smell like tobacco. I understand. I get it. So, the porch and the back deck are OK and in cold weather I have to grin and bear it. The thing is, it does not need to become a pissing contest: you or my pipe is a bad way to go. She will sit with me by the fire on the back deck, or on the porch, when I have a pipe. My compromise is that I will usually smoke an aromatic when she is on the porch with me. They aren't my favorites, but more and more I don't mind them and I'm happy to share a glass of wine on the porch with my wife -- an aromatic in the pipe is the least I can do. By the fire, anything goes because the fire on the back deck pretty much overwhelms anything.
At the end of the day, I'm lucky to have, and happy to have, a wife who gives me no grief about smoking a pipe and about spending $100 or more a month on pipe tobacco. She's more than I deserve. I think it works, for us, because she has her own life and career and I have mine. We are together because we want to be, not because one of us needs to be.
