About A 15 Year Old Guy Commenting On 12 Year Old Girls Pics?

This guy in my school added me on facebook which is fine because we go to the same school. Later i put a new profile pic and he commented “nice phone” then i said “lol safe(thanks)” and he said “oh yeah nice pic (wink sign) then a few days ago he inboxed me saying “hiya you ayt (alright) ?” I replied “hello” then he said “like ur pp” which was of me and im like “lol isit” and he said yeah. What’s he tring to say do you think? Because in the past two/three months i have been asked outtwice and getting comments from guys and im not really usedto it and i don’t know who i like so what is this 15 year old saying? Does he like me or just being nice?
