My boyfriend doesn’t want our baby

So I’m 28w3d pregnant. My boyfriend and father of my child does not want our son. He tells me he will lose his family and that he’s to young to be a dad. And yes he is young. He’s 17 and I’m 19 but we’ve been together almost a year now and he tells me he wants to be with me but he doesn’t want the baby. I don’t know what to do because I’m in love with him and I don’t think I can take losing him. I don’t know why I stay with him if he doesn’t want our baby but I’m still hoping he will come around and stay with me even after he’s born and take responsibility of the baby we created together. What should I do? Leave or stay hoping he’ll stay with us and be a family
