how to co-parents?

did any of yall actually manage to successfully co parent? we’re not married , not really speaking… used to be on terrible terms but now slowly speaking. I send their family pictures now and then. I grew up without a dad & I really don’t want my kid to go through the same thing. But baby daddy is not really asking about the baby. he met baby once and that’s it. As much as I love spending time with Baby I want him to spend some time with his father too. Want to suggest for him to come take baby on weekends but I don’t really know how to bring it up. Actually I don’t even know anymore does this man even wants to be in my baby life:,) what would you do if you were me?
