Staying will not fix her problems.
You need to find the courage to leave, if not for yourself, for the children who do not need to be further damaged by your wife's destructive addiction.
Ophelia is right.
I'm sorry you are in this dangerous situation. Please protect your children and yourself. Here's a link I found for some resources in the Bay Area. It looks like it could be a good place to start.

Another option is to contact the United Way for help. It also would be wise to consult an attorney so that you can find a way to keep your children in your home -- they should not be the ones displaced.
Take good care. There are good people here. Check out the Friends and Family forum. They've been there, too.
