Glad to see you are taking action to take care of yourself - I am sorry you need to be going through this! Being in CA myself I have a little bit of experience....I would suggest your first stop when home is an attorney or a service that will start divorce proceedings for you. Filing for separation will go a long way to giving you the ability to keep things financially and physically separate - police will be able to help out more too if need be.
Hang in there.....your life is about to get a lot calmer!
