My question involves marriage law for the State of: CA

My boyfriend just kicked me out of his house that we've shared for over 6 years, took my key & has kept my personal posessions, and will not let me get them. He also has by small business supplies & won't let me have them either, costing me $$ and credibility in my business. I am now homeless & living in my vehicle. Please advise, either officer standby or take his house from him & kick him out.
