My ex-guy no longer works at the same company as I do

I have a LinkedIn account. I don't use it often. I check in every couple of months.

My ex-guy and I are connected on this platform. I checked in yesterday. I found out that he had left our employer last month.

Part of me is relieved that I will never bump into him at the office. I don't know how I'd react if I did see him again. 

We started working for this company the same year. He started six months before I did. We didn't know each other until the following year. We started dating then.

The other part of me is curious as to why he left. Naturally, I haven't spoken to him in years and won't ask him.
