I know it's long but please help?

My bf lives in a different state than I do we have a really strong relationship and everything is perfect. We are both 18 I'm still in high school and he has graduated and has a good paying job. He wants me to move in with him when I graduate in the moment I was excited and said yes but now I'm not sure. I know my parents won't be happy if I do and they are under the impression I'm going to college and I really want to. I just don't know how to tell my bf I don't want him to think I don't want to be with him or anything but I feel like I need to go to college. What should i do? How should I tell him? Should I just move in with him? Any advice? Thanks in advance :)
