Should I or should I not

WARNING: KIND OF LONG POST!!

So there’s this guy thats in two of my classes and he’s super cute but I don’t think he’s boyfriend material based on things he’s said. At times he seems responsible and other times he doesn’t. He always post these things about how he’s lonely and to slide up if we wanna change that. I kind of want to but I kind of don’t bc I don’t think I’m his type. But he also takes ugly pictures of me at random times and sometimes he post them sometimes he doesn’t. I don’t know what he does with the ones he doesn’t post. So I need y’alls opinions on if I should say something or not.
