Yay!! Trish, I know you're bricking it hun, don't. Just decide here and now, it's enough. You have done this enough times, you know the pitfalls, you know the triggers, get some plans laid out.
As for hubby smoking, you are gonna use him (in the nicest possible way, well 2nd nicest lol) to secure your quit. Every time he lights up, you are going to remember "I don't have to anymore, because I'm free". Will feel silly a bit but trust me on this. Occasionally watch him smoke, does he look relaxed and overjoyed, nope, some chemical is gonna catch in his throat, he'll make a face or cough - THAT is the real smoking, then get smug because hey, you don't have to do that anymore.
Write down a list of reasons you do not want to smoke. Keep it with you, read it when you crave and remember. It is your brain trying to drag you back to addiction, there is no pain, there is nothing other thanthoughts.
I know you worry you lost a quit at a month, that honestly bears no relation to this quit, other then what you learnt on that practice. Head up, chest out and welcome to your non smoking life. It may be a bumpy ride but christ trish, it's not like you haven't seen some bumpy ride with this family (meant in the nicest way). You are the queen of handling stress in a calm and diplomatic way, you just need to shift that to not smoking and trust yourself :)
