Boyfriend spends too much time with baby mama. What should I do?

We've been going out for a week now. I just feel like he spends too much time with his baby mama. I understand they have a kid together but does he need to spend time with her too. I'm happy he taking responsibility for his child. I know that she will always be in his life but he doesn't even have time for me. We barely talk, what's the point of being in a relationship if we don't spend any time with each other. Why did he even ask me out if he know he doesn't have time for me? We've been friend for months before we became a couple and he never mentioned anything about having a child till now. I would think that will be something that you tell your friend my question is what should I do? Should I talk to him about it or just break up? I don't want to be selfish and let my needs get between his child and I don't want to make choose or anything. I just feel like crying, I just want to spend time with him but at least talk to him, I really like him. Does he really have to be that close to his baby mama if their broken up? Maybe I'm just being jealous and selfish.

It doesn't bother me cause he spending time with his child. It just that when she comes to his house with the baby she stays the whole day instead of dropping her off she stays till midnight or longer.
