I'm an indoor smoker, which I restrict to my basement rec room, and I take simple steps such as- opening a window/running a fan, and most often than not I just wait for the wife to be at work. No need to force the issue with her, or agitate deliberately, and I like my current set up as it is. I know she doesn't like it, but to be honest I really don't care. It's my hobby and one that I enjoy greatly. She knew that way before we married. Besides, I'm 39 years old. I didn't take any crap from people (family, or otherwise) when I was younger and I don't intend to start now. Just how I'm wired, I guess. She has never asked me to do any of the precautions I do, I just do them.
Everyone's situation here is different though, I respect that, but if my wife ever was the type that was a "SWMBO" we'd have never lasted into our 13th year as we are now. That goes both ways as well. We do our own things and give each other our space when needed.
I've said this before, so I will say again to the ones looking at setting up a smoking room- definitely don't do carpeting. Get rid of it if it's already in there. I replaced my rec room carpet with resilient vinyl tile this summer, and the difference in any lingering stale aroma of the room was huge!
BTW- I'm baking a tin of OGS as I type this, just sayin'... :
