Terrible neighbors

So I’ve lived in my apartment for 5 years ever since I moved in I have had problems with my neighbors. I have been seeing this guy for a year now and while I was in Tennessee he befriended my neighbor and I asked him not to he did anyways. Finally I gave him an ultimatum that he is to stop hanging out and talking to him or I’m gone because I will not tolerate his disrespect toward me and being friends with my family. Anyways fast forward a few days later I come outside and see them talking i guess my neighbor was telling my boyfriend that I need to let them be friends. Anyways I walk up to them and my neighbor tells me to leave to where I respond I don’t have to that’s my boyfriend and I’m having his baby. From then my neighbor stepped two inches from my face cursing my son saying he’s going to die after he’s born over and over again. He’s a native and I hear they do spells or witchcraft idk if it’s true but is there a possibility he could have? I’m super worried for my unborn baby now.
