Long distance not much of a relationship

So in grade 10 I met this guy and weve been friends since then. When I

I met him I was with another guy but then we broke up, we still remained friends and then I moved 4 hours away and for the past year and a half (since I've left) weve still talked and whenever I was around we'd hang out. Over the summer I told him I've liked him for the past 2 and half years I've known him and he didnt tell me he liked me back till January. I was visiting my sisters and I pretty much spent every day and night with him. We would cuddle, hold hand, hug and kiss and just... act like a couple. We talk every day like we are but now that I'm gone again I feel like hes gonna stop talking to me because hes too hurt and wont want to deal with this. I'm the only girl hes ever done anything like this with, hes not like other guys. He doesnt drink, smoke, he barely even goes out. When he does he goes out to McDonald's with his friend or goes to that same friends house to play video games. Hes not a womanizer and I really really like him.. how do i handle this situation?
