Boy help

Okay so I've been talking to this 11th grader, I'm 14 and in 9th grade. He has said things like you're cute af, you're goregeous, you're beautiful, wanna chill, ur mine, I wish I was laying next to you, and meet me on the first day of school I'll walk you to your class. That's about it and repeats some often so what do you think all of this means and what should I do/say.
