If your mom helping you is an option, have her take you to meet with an attorney and see what your rights are. If you have been living together for a lengthy period of time, you may have the right to palimony and a portion of the property. And, this may be over the top to some, but depending where you are in California, camping is an option. I had a friend who borrowed a tent and some other items, took her dogs and went to campground and stayed while leaving her abusive husband. She was able to file for divorce, and get him kicked out of the house, and then get maintenance (alimony).

I would rather live in a tent in a decent campground than lose my dogs or be in a homeless shelter.
