Am i wrong ?

I'm 23 weeks pregnant I'm only 17 years old soon to be 18 I'm a single mom the father of my child has been so abusive my whole pregnancy it hasn't been physical but mentally he constantly tells me he hopes that I die and that my baby dies and what he'll do to me so I finally had enough and left at 19 weeks he was also cheating on me and the girl he cheated with is also pregnant now I've told him that I do not trust him to be around my child when he arrives he says that I'm jealous and he'll take me to court and take my baby etc. But I honestly do not trust him it has nothing to do with jealousy I'm just afraid he'll hurt my child I have multiple messages of him telling me he'll kill me and telling me that he hopes me and my son die is that enough to prove in court that he shouldn't be around me or my son ?
