Hello Pearly,
You sound very young. You are a dreamer and dreaming is wonderful fun but don't let it get painful by imagining the dreams are real.
Don't read too much into his glances in your direction. If he is interested in you in a romantic way he will let you know for sure and you will not have to guess. If he doesn't let you know, and only looks at you occasionally, as you describe, well that is what acquaintances do.
If everyone we look at thought we were in love with them, the world would be very confusing. Looks mean nothing.
