If you don't like her life, don't pursue it. Don't expect her to change for you. Change it for a while if you can, but not for you all the time, she will be psychologically unbalanced. So, think for yourself. Have you accepted her life? If you can't accept it, then give up. The deeper you go, the deeper you get hurt, and even hurt two people. I wish you happiness. I don't smoke either.
