bond between yourself and child's father

I just have a quick question. Me and my daughters father have ups and downs in our relationship and sometimes we just wanna call it quits but don't do it for the sake of our child. We've worked on us to make it better for all 3 of us. I guess my question is... if we were to break up is there really going to always be a special bond between us cuz of our daughter? I've heard some people say there will always be that special connection between two parents. And then some people say otherwise. Any opinions on this? Just curious as to what everyone thinks! ☺️ Please no negativity.
