Why do you need to do anything?
If he asks you out, and you aren't interested ... You politely decline.
I think this guy in my English class likes me but I like someone else. The guy that I think likes me is nice, confident basically a nice guy the guy I like is in none of my classes what do I do?
If you want to speak to him, go up and ask how his weekend was. Learn how to make small talk with people. Observe their body language. These are skills that should be taught to everyone so you don't spazz out when you speak to someone. Good luck.
