Does it mean anything if a guy likes a girls post?

So I’m into this guy we met in the beginning of the year and we only spoke last semester since we had one class together and text now and then he would wait for me after class or before when we arrived at the same time but I do not know if social media is a big thing now I’ve noticed he’s been liking other girls post on instagram and I am not sure if he’s attracted to them?
