Leaving abusive relationship please read

I have posted on here from time to time about the relationship I am in & that I think it may be abusive & y’all obviously confirmed that I am. Physically, sexually, & verbally. I think today was my last straw & that I am actually done but I am seriously SCARED that I will get roped back in. Please someone help me & give me advice. I have already separated myself, I am at my moms house but all my belongings including a baby blanket that is important is there at is home where I was staying. He is already not letting me take one of my cats. I am scared.
