Help! How can I get out?

WARNING. DOMESTIC ABUSE AND VIOLENCE.

I no longer trust my partner and want to leave the relationship, but I am afraid of how he might react. He has abused me twice. The first time, he kicked me in the face three times, splitting my head open so badly that I needed 10 staples. The second time, just this past weekend—two months later—he attacked me in a hotel room for three hours. He forced me to drink 3 of the 1.5 bottles of soju in large amounts, as in half a bottle each time. He pushed me down by my neck, pulled out large clumps of my hair, and left me with a black eye, swollen cheekbones, and scratches on my neck.

I was able to escape when he passed out from the soju andI ran out of the room and asked the hotel staff to call the police. However, the police did not arrest him. They only ensured that I left safely in a taxi to go home.

Afterward, he sent me multiple texts blaming me for making him angry. He insisted that he didn’t actually hit me this time, so I shouldn’t be upset. When I told him that just because he didn’t punch me doesn’t mean he didn’t hurt or terrify me, I even sent him pictures of my injuries, but he still refused to acknowledge any wrongdoing. Instead, he continued to blame me.

I told him I want to end the relationship because I can no longer trust him, but he simply said "no." The next day, he spent his time drinking soju and sending me photos of himself drunk, saying how much he misses me. He also admitted that he lied when he promised that if he ever hurt me again and I wanted to leave, he would let me go.

I am terrified that if I break up with him, he will come to my door. I have no way to move, and I fear going to the police because I don’t know how he might retaliate.

I have a dog, which makes it difficult to find hotels or motels to stay in, and my limited funds make my options even more restricted. I feel trapped and don’t know where to go or how to leave safely..

My boss at my school knows about all of this but cannot change my apartment.
