I need relationship advice, I'm so confused. Help! What do I do?

So lets start out with some background information. I'm 16 and will be graduating next May and headed off to college. I live in Texas and have been planning on going to Texas A&M to major in Biology and minor in business and then continue on to Dental school at Ohio State to become an Orthodontist. My boyfriend is 23 and dropped out of Ole Miss to take over his dad's agricultural business. This unfortunately means that our plan of him moving to college station when I move up there is out the window. This means it will probably be about 12 years before we can really be together and living together and really like starting our life together. He understands that he has put me in a really difficult position and has said he would understand if I wanted to end our relationship. So now I have a difficult decision to make. I could either A) Go to A&M as planned and then join him in Mississippi after I finish my education B) Do my undergrad studies at A&M and go to dental school closer to him C) Do all of my schooling closer to him D) Break up with him. I really need advice. We just told each other we love each other and this is the first guy I have truly loved. Yes, I do realize there is a big age difference and that sort of worries me that if I got to school close to him somewhere I don't really envision myself and he finds someone else I will be miserable. I also have a knack at messing up good relationships because I'm not great with commitment. Agh I don't want to give up just because I'm scared but at the same time I don't want to be the idiot girl who follows the boy just to be dumped and made to look like a fool. Help pleaseeeee. Any Advice would be greatly appreciated.
