I don't smoke inside for a few reasons. At my own home, I live with other people, some of whom smoke cigarettes, and smoking is done outside or in the garage. Living in Southern California, this rarely presents too much of an obstacle. I really don't like the idea of cigar smell permeating everything I own. My boyfriend is also a cigar smoker, and he doesn't smoke inside his apartment either. We both agree on this policy, and if we get a place together, we still won't smoke indoors. (Unless we build a well ventilated cigar lounge.)
Yes, relationships are a give and take situation, which also includes being courteous to your significant other, if you expect them to be courteous to you. If your S.O. decides they really can't stand smoking in the house, and you insist on doing so, be prepared for them to be unhappy about it. A non-smoker has just as many rights in the house as a smoker, and it may require some compromise. If you have the space for a designated smoking room, that is great. If you don't, I can understand not wanting it in the rest of the house.
