Old colleague (male) unfollowed me?

We worked together ~6yrs ago and he asked to follow me after he left the company. He is very active on social with curated photos and stories. Admittedly the guy had interested in me when we worked together tried to make some advances and after the IG add he did reply a story (which I replied but he didn’t say anything further and he never tried again so I didn’t think much). Pretty sure he has been single all the years (I’ve never posted any guys on my social media personal preference, only things I want to share food, friends, travel pics etc) but I noticed he unfollowed me a few months back- but he follows a few other coworkers (including 2 other women I follow who are both married and also active on IG). He also kept me as a follower which was even more annoying. I couldn’t care less about the guy but What gives? I mean after all these years what happened lol it was so unwarranted.
