Walk away or try harder?

My boyfriend and I are very much in love. He is the first guy that i’ve ever had so much freedom with, and same for him. We go on great trips, we stay the night with one another. We do everything together. He is so good to me. I love him more than anything in the world. Over the past few days I have it a very hard spot in life. I will be staying at home going to a local college and he will be going an hour 1/2 away. I am struggling so hard. I think this will put a serious strain on the relationship. We trust each other, neither of us are controlling. We don’t get jealous, we don’t argue. We are so happy. But this decision has made me wonder if it would be better to go our separate ways or try to make things work. I don’t want to leave, he doesn’t want me to. He tells me that he KNOWS, we can make it work. I’m scared that with the time apart things will change. I’m so lost and heartbroken. Please give advice.
