I think you’ve gotten great advice and I’ll just add a couple of points from my personal experience. He could be playing with your emotions on purpose, he could be unsure and likes the thought that you still want him so he’s trying to keep you “on the hook” as an option (if that makes sense). Or….he’s just being friendly. Friends share links to things they have in common and like each other’s pics. I have a male friend that I once had an attraction to. I met a great guy and am no longer interested in that guy that way. But when I was on Facebook I used to send him links to Civil War things because we both had an interest. And I liked most of his pics because we have very similar likes so I tended to “like” them in real life. My current boyfriend liked pics of ex’s…sometimes of them with their current kids/family or just things they were doing. Because he truly still appreciated those parts of that particular person, not because he still had feelings for them or wanted to get back with them.

I wouldn’t read too much into it unless he starts actively pursuing you. And even then I’d tread carefully with a guy that is “angry” at you and has compared you to a woman he recently divorced!
