advice?

so this boy and i used to be a thing or whatever. and we may have exchanged some photos, but now we barely talk. and he’ll be in class like “oh don’t you hate it when girls use the no screenshot sticker on Snapchat?” . and he says this like to my group but not directly towards me even though that’s exactly what I did to him 🤦🏼‍♀️or i told him his muscles and abs were like a big turn on (when we used to talk) & now he’s always taking off his hoodies in class to flex, or he’ll say something like “what are abs” and show them off. like is he being petty or is it just me???
