Only staying with me because I’m pregnant

My boyfriend is only with me because I’m pregnant. He keeps saying he’s worried if we aren’t together that he won’t have a part in the pregnancy and my previous son with my previous partner. I keep telling him that we don’t like each other anymore and that it’s even more unhealthy to stay together just because I’m pregnant. But he keeps saying he wants to work it out. I know that if I wasn’t pregnant we probably wouldn’t be together. Idk what to do. I want to actually be in love and like the person I’m with and vice versa. We just don’t get along.
