Unfriended a coworker, he’s angry and has written a public post about it on Facebook?

My fiancé was having issues with a male coworker who I’ve known for quite some time. He often called and texted me after work. In the end, I decided to just unfriend him.

A few days later he found out that I unfriended him and he blocked me. Fast forward a week, I was told by a mutual friend that he’d written a public comment regarding what happened between us on Facebook.

How should I react? I’m guessing it best to ignore this? What if I come across him again at work ( although I can avoid him)
