Does my first love stalk my Facebook page?

So I met this guy in 7th grade. I caught him staring at me and it was love at first sight. We dated for year after that on and off until we went to college. We never got into any arguments or got upset with each other, it was always distance keeping us apart since I wasn’t allowed to date growing up and he played football at another college. I was told by his parents that he was still in love with me. He is now married to his college girlfriend and I am seeing someone. I posted a throw back picture the other day and he didn’t like it, but he left a heart reaction on a reply I made to someone else’s comment. He also watches all of my stories sometimes. Is he checking out my profile? Does he possibly still have feelings for me?
