I am not very up to date w/ social media & experience w/ guys, so I’d appreciate Overall advice on how to move forward. This guy & I are mutual friends & check on one another every blue moon. I don’t doubt that he likes me but we’ve followed each other on ig for a long while & out of nowhere he decided to go to my profile & like my pics old & new. Why? & should I be liking his old pics back? Do I just let it play out?
