I have a confession to make
. I am a closet smoker....well not entirely in the closet.
My husband and I both quite years ago, I started again and he hated it. So I don't smoke around him, I don't smoke in the house unless he is working out of town for a long period of time and can air it out before he comes home, and I smoke much much less than I used to - maybe a pack or two a week, instead of a pack a day.
My point is that it is unhealthy for me to smoke and I know that I will need to stop someday soon (okay I'm stalling), but I don't smoke in his space and I don't spend much on cigarettes.
Not that any of this will solve your problem, but she should perhaps keep her smoking out of your space, especially if you are asthmatic.
And I really do pray that she will be able to give it up soon.
