Smoking Inside....

I have smoked since long before she met me. She knew I smoke; she even gave me the pet name "dragon."
We live in a state where smoking is not allowed inside any public building. I have to go outside to smoke when I am at work, at restraunts , EVERYWHERE. The only place I can smoke in comfort is in my own home. I shouldn't have to go stand in the cold or the rain at my own house. When the weather is nice, I don't mind all that much, but it is degrading to be forced outside in inclement weather like a dog. I won't be treated that way where I live.
Further, it is extremely inconvenient to have to stop whatever I am doing to go take care of a craving. I play a lot of online poker(real money, not play money), and with all the ups and downs, close calls and adrenaline rushes, smoking helps to keep me calm. Am I supposed to just let some of my chip stack get blinded away while I am outside?
I DO undertand that to non-smokers the smell is unplesant and I am more than happy to try and find some compromise. I have suggested having a designated room to smoke in. I can put the computer in there. I have suggested putting a fan in a window pointing out, to suck the smoke out the window. I am COMPLETELY open to other suggestions on how we can work it out. Apparently this isn't good enough for her.
Why would I want to sell our couch or bed, anyway? Besides, anyone who is buying a used couch would care more about getting a good price than if it was owned by a smoker.
We have been talking about getting married and I fear that this situation bodes ill for our future. It is naive to think that we will never have disagreements, but what gives me pause is that she seems unwilling to work together to solve a problem. She wants HER way or nothing. Whenever I don't just cave and give her what she wants she says I am being mean or "ugly" to her. I mean, we're supposed to be a team, right?
