Even though I've only been married 8 months, I've definitely leaned on my parents and my wife's parents for some advice, as they have both been married over 30+ years and the one word is "compromise". I'm gathering that you smoked when you met, so obviously she knew you smoked and that you needed your space, so that should be a non-issue and maybe there is something else that she wants and you might have to give a little bit on something else to get your previous smoking freedoms back. Hopefully you can get it worked out.
