What's the best way for a smoker and non-smoker to live together in relative peace?

I gave up smoking years ago and my husband continues to smoke. I can't stand how it smells now! It affects everything - your clothes, your furniture, your breath...and in winter when you have the windows closed a lot it's worse.

He won't give up. That's out of the question but it causes friction between us now. What can I do to find some kind of compromise? The smell of it really gets to me and appealing to him on health grounds falls on deaf ears. Maybe I'm expecting too much.

Any ideas would be appreciated. Thanks!
