Crush’s big fat ego

Okay so there’s this guy I like but not really sure about him. We don’t go to the same school so a lot of our conversations are basically just texting like on snap. And he talks a lot like he’s full of himself? It could be a defense mechanism or maybe he’s really self conscious so he plays it off like he thinks he’s good looking? Or maybe his ego really is just THAT big. But it’s rly hard to tell because its over text and i dont know if I should go for him bc right now it’s like a friendly crush. Also i dont even know if he likes me because in the past he’s asked my friend about me but through text he’s just so passive
