As Dreamofunity said, it's not a physically addictive drug but, as with almost anything, it's possibly to become psychologically dependent on weed. As it's become a part of your normal daily routine you will need to change most of what you do that has links to weed in order to quit successfully. It'll take a fair amount of willpower and self-restraint, but maybe you could try rolling joints with just enough weed in them that it tastes of a joint, gradually wean yourself off? I don't really know that much about quitting weed, maybe it'll be easier just to stop.
It's important that you keep yourself away from things, places, people who are likely to tempt you to smoke again. Throw away grinders, skins, ashtrays (if they're only used for joints); try to stay away from friends who smoke weed (at least for the first couple of days) and explain to them that you're quitting and need to not be tempted.
Do you smoke cigarettes? Maybe try replacing your morning joint with a fag instead so you're still waking up and smoking something.
If your husband also smokes weed, you'll be able to support each other through the toughest parts. If you're really serious, delete your dealer's phone number so there's no way of getting in touch if (when) you're feeling weak.
You could also try making a list of the benefits (health, financial, etc) of quitting and keep it somewhere you can look at it and remind yourself of why you're doing this.
As others have said, it will probably be useful to look at why you started smoking weed, and why you have continued to do so for the last 2 years. It might be that you need to find another way of coping with whatever those reasons are.
I wish you all the best with this.
