Left my abusive relationship and autism is drawing me back in

My boyfriend who i moved in with out of state was becoming more and more abusive and my uncle back home helped me get a flight back home to where he was. Shortly after he was admitted into hospice and then passed away last week. I’m in St. louis and i’ve tried calling 211, all of the domestic violence shelters in my area and no one has availability to take me. 211 won’t help me because technically i have left the abusive boyfriend. I am so lost and scared i truly believe my only option is going back to him and apologizing for it all. ;(
