Emotionally Abusive

Please help me gain the courage to leave my abusive boyfriend, he threatened to hit me, choke me, pee on me.. this morning he took my phone and hid it from me. When I tried to get it back he twisted my arm. This is the first time he has actually put his hands on me but not the first time he’s threatened me. I’m scared, I don’t wanna lose him because I love him but I don’t wanna be hurt. I feel so emotionally drained and depressed, he calls me stupid and a hoe and a bitch. He tries to play them off as joking but I know that he is serious. I just need encouragement.
