Does he like me

This guy and I have known each other our either lives. I'm 18 and he is 19 turning twenty in two weeks. I have liked him for a while now and just recently we have been texting daily all day since last week. He hides his feels well unless he tells you. But how do I know if he sees me more than a friend he will sometimes include emoji such as ❤️💕😌😏. How do I know if he is just being friendly or flirting. By the way he has only had one gf his entire life
