I'm sorry you are having to deal with this, you DO need support. Your situation does sound very similar to that described by some spouses of recovering alcoholics. Perhaps give Alanon a try if there is nothing specific to your situation? Much behaviour in addiction seems similar regardless of what the substance or negative behaviour that a person is addicted to, and perhaps there are similarities in recovery too?
whether there is or not, you will find a group of people who understand your anger, and can give you an outlet and some physical support.
