Co-Friends 

A human that worked with another human

Back when we were co-friends, I liked what you had to say.

Co-Friend

A person you are friends with only because you work together. (A Co-Worker Friend). If one of you left the job, you wouldn't keep in touch.

"Ashley is my best Co-Friend, we take all our breaks and lunches together, but I would never ask her to hang out after work because friends and work don't mix."

co-friend

a friend who is only your friend at work

At work I do not have any friends, only co-friends and that is because friends at work do not mix.

Or
I only have one co-friend at work and that is Kendhal. We do everything together like take lunches and breaks together, we email each all the time but one thing we never do is hang with each other outside of work, because we are only friends at work.

Comfriendship

A connection between two people (usually ex-partners) where romantic feelings and traditional friendship obligations are completely gone, but a deep sense of comfort, familiarity, and zero-pressure understanding remains. It is a compartmentalized bond based on shared history, with absolutely no expectations for the future.

Person A: "Are you and your ex getting back together? You guys still talk."
Person B: "No, definitely not. There's no romance and we aren't exactly 'friends' either. We just know each other too well to be strangers. It's a comfriendship."
