He's obviously trying to move on. You should at least give him space even if you guys aren't together still. Thats probably what he would want.

Oh how social media rules our lives. Before FB, Twitter, IG, Snapchat, etc. no one had these insecurities/worries or was bothered by such little things (just my opinion on social media, not of you or your question).
Honey, he's trying to move on. Being friends after a relationship isn't easy and it takes time. You don't just instantly go back to being friends. Just be patient and give him space and time. What's meant to be will find it's way.
