Dating a man with a kid

I’ve been with my boyfriend for a year and some change. I have a lot of love for him but I hate him at the same time. We don’t really have the same goals and I don’t see him going very far in life but that doesn’t mean he won’t. I can’t see him being able to provide for me and our family if i were to get pregnant because he’s never held a steady job as long as I’ve known him. He’s also gone months without work which is such a turn off. But my main problem in this relationship is his kid. I don’t have any kids and I’m only 21. I didn’t think I would have a problem with him having a kid until I got too deep in the relationship. It’s really a turn off for me at this point in my life. I don’t like that the man I’m with still has to talk to his ex because i feel like you shouldn’t bring past relationships into new ones(my opinion). And I don’t want to be a step mom now or ever. He won’t accept that and says I’ll change my mind. But I want my own baby daddy not someone else’s 😂🤷🏽‍♀️ but I’m afraid that if I leave him I’ll never find someone who loves me and also has the qualities I want in a man. What are your thoughts?
