how to quit while living with a smoker?? Help!

Hello all :) I have decided that I want to quit smoking for good. I am 31 now and have been smoking for the last 6 years. Im so dumb for even starting. Who starts smoking at 25?? My parents don't smoke, my sibilings don't smoke, but for some stupid reason at 25 I started this bad habitt! The reason I have decided to quit is because god has blessed me with a beautiful baby(6 months now) and I don't want him to grow up with out a mommy or to grow up to be a smoker. Anyhoo Im here because I need some advice. My husband smokes and refuses to even try to quit. I find it triggers me to want to smoke when I see him smoke or smell smoke on him.I get very anxious, my heart starts racing and I eventualy cave in and have a smoke. We have have always smoked out doors. My husband gets very frustarated when I ask him to quit with me. It has caused many arguements between us. If anyone else has sucsessfuly quit while living with a smoker please share your secrets with me. Any help would be greatly appreciated.
