My abuser broke up with me, we live together and I have very limited funds. What to do???

Yesterday afternoon after a 6 hour fight, my then-fiancé called me on the phone to end our relationship, because he said he knew hed never be able to change, stuff like name calling, shouting, etc... though he'd promised to in years past. We still live in the same house. I have a dog, but I have no family or friends in the state, and almost no money (hence why I didn't leave him already). I do have a credit card but idlike to avoid getting into debt too much. I just got a new job I started about a month ago.

Can anyone offer advice in this scenario? Pretend there's no one to call, what then? Sleep in the car and shower at a Rec center? The only other thing I can think of is getting a storage unit and slowly moving my belongings there, and then putting a blow up mattress there in case I need to flee. We're currently broken up and sleeping in separate bedrooms. He's being kind innpassing around the house but it's uncomfortable and I'm scared hes going to snap all of a sudden when I least expect it.
