What should I do ? Idk how to feel

In the beginning of my pregnancy my baby dad told me the decision was mine to keep the baby or not,, now I’m going on 4 months pregnant && he keeps saying he doesn’t want her && he’s not ready & since it’s too late to get rid of her he’s gonna kill his self when she gets here or before && that he didn’t mean it when he said I could choose he juss wanted me to stfu and be happy ,, what should I do ? 💔this is heartbreaking knowing there’s nothing I can do and I don’t want him to hurt hisself either he’s sent me pictures of guns && plans to hurt hisself. && Yes we were inna relationship before all of this and before that he was my best friend I’ve never seen this side of him and I know this isn’t him but I can’t say that because it is him because he’s the one saying it idk what to do his mother is in his ear he’s saying his mother hates him because of me and the bay and I just feel so alone and heartbroken
