What are you hoping for?

As a technically-minded person, I'll just come out and say that I've only ever met one founder that was my friend, and they were a deeply technical person. I don't have anything in common with MBA graduates or post-management types that spend their life reading Medium posts, browsing Linkdin or tastemaking on X. I'm willing to work with these people, but asking to be my friend is a dead end.

I'm not saying that your cofounder is a carbon-copy of me, necessarily. But it sounds like you're conflating personal needs (eg. "I need friends") with your workplace situation ("my cofounder is not my friend"). You could rectify this by expanding your personal network and letting your technical cofounder focus on the technical stuff.
