I need to let this out

I've been holding this in for such a long time but I don't know what to do anymore. I'm a senior in high school and I've been in a relationship with my boyfriend for almost 3 years. I would do absolutely anything for him and done absolutely everything possible for him. We've been through hell and back in our relationship more times than I can count. We made it through his little brother having a stroke, him deciding to up and leave and move over 1000 miles away, we made it through things that most couples would never even think could possibly happen. But now I'm looking at colleges and time is running out. My parents want me to go away for college so I can have the experience of being on my own. My boyfriend wants me to stay so we can work towards getting married in less than two years. I don't know what I want. When I went on this college visit I just got this great feeling about it and I barely even talked to him about it and we got in this massive fight. I want to spend the rest of my life with him and that's the only thing I know that I want. I think I might want to go but I don't know. I've been so busy trying to make everyone else around me happy that I forgot about myself and I don't even know how to make myself happy. Lately it's all I can think about. What should I do?
