Welcome to SR, bluebird.
I suggest you visit with an attorney and find out your rights. If you have a joint bank account, it would be wise for you to open an account in your name only, preferably at a different bank, and move as much of the money as you can into your own account.
If your husband isn't working and isn't doing anything other than drinking, then you cannot depend on getting any financial help from him. If you aren't currently working, you may have to get a job. The one thing you CANNOT do is just wait around to see what happens. You must be proactive to protect yourself and your children.
