Smoking..ugh

I have been thinking a lot about quitting smoking..again. The last time I tried to quit my husband refused to stop smoking in the house. Actually he would sit right next to me on the couch and light one up! I know, not very considerate. Needless to say I wasn't very successful and every so often he will try to bust my ass about it and I just tell him that the support system I thought I would have had just wasn't there and yes that means you! I think I may try to quit once again, nobody said it would be easy. Now would be the best time really, since we don't smoke in the house since we have moved and have to go outside, well I am not sure if I am up to freezing my butt off all winter. My fear though is I will gain the weight back they I lost and have to end up trying like hell to lose weight weight, the weight I already lost. I know I shouldn't think that way, quitting smoking would be much better for my health but it is still a concern of mine..besides I could save some money, alot of money!
