need advice

okay so i’ve been dating a guy for almost a year. he has a one year old with another woman. a few minutes ago we were just sitting down in bed and she was playing with her bottle and he was playing on his switch. well she’s been in a fussy mood all day and was finally in a good mood, playing with her empty bottle and feet and her tablet toy. she threw her arm back with her bottle in her hand and hit my boyfriend in the face with it. he got so mad he grabbed the bottle and threw it at the wall very aggressively. he has been violent with me before but has never done anything like that with his daughter in the room. i’m still shaking because of it and i’m so angry at him for doing that around his daughter. I grabbed her and left the room to get away because I don’t feel right taking her out of the house. after u got into the living room he yelled that he never wanted a kid. I didn’t reply because it was dumb to say that, if he didn’t want a kid he should’ve been more careful so idk why he said that. what do I do? i’m so nervous and still shaking. he was also violent with his baby mama before and I didn’t know that until after being with him for like 10 months.
