long distance

I have been with my boyfriend for nearly 10 months. I am currently a senior in high school but I am going to college starting in august and the college is 4 hours away. My boyfriend is currently in a community college in our home town. I love him so much and I don’t want to be with anybody else. he treats me so perfectly and i just see the love in his eyes each time he looks at me. i can’t imagine the thought of losing him:( any advice on how to deal with long distance relationships?
