Long story short theres this guy I used to have a fling with 2 years ago he lives in europe and im from USA, im kind of in love with him xD and im moving to europe soon to get a degree and plan to try and meet up with him but for now i've kinda been crushing "does he like me? is he just being polite?" kind of thing. I had him unadded/blocked most of the 2 years because I didn't want to see him move on with other girls but recently i added him back and he messaged me and after i told him about me moving to spain and "miss you!" he said "ahaha thats cool good luck, i miss you too, i wish we gonna meet again at some point." then convo ended.

Then like 3 weeks later he invited me to like his software company page, it was new so i assume he invited other friends as well. I accepted the like request. Then a couple days after that i updated my profile pic and he liked it which stood out to me because he rarely likes my stuff. To the thing im asking about, today i commented on a guy friends facebook picture fire emojis and his page is public so it goes on my news feed for all friends to see. Like 20-30 minutes after i did that, the guy in question comments on this meme picture and tags one of his girl friends. Now the only reason i'm even asking about that is because he barely uses facebook like that, i know this because i follow him on facebook and nothing ever comes up about him. So I was thinking maybe he was copying me.

TL;DR- A guy who i like who never comments or posts on facebook, made a comment on an old meme tagging one of his girl friends after I commented fire emojis on a public picture of one of my guy friends. Overthinking or no?
