I want to be with him but he doesn't feel the same. Advice!?

It will be three years in April. Our relationship has been great and filled with no regrets. He wants out. We've been having the same conversation for the past 2 weeks ; he says I am stubborn and too independent for him whereas I tell him he doesn't give me enough time. We are both going to different colleges but they are only 45 minutes away. I really want to be with him and work this out because we have been through much worse, but he says he thinks it will not work out. He told me he was completely miserable so I have been doing everything in my power to make him happy with me. I thought it was working, but I guess I was wrong. I am a very optimistic person and I can see us together because I want it. I can tell he doesn't by the tone in his voice. He recently became a frat boy and I know that has a lot to do with it. He wants his freedom so he won't have to be worried when he dances with other girls or gets drunk with them. I don't know what to do. He said he is not breaking up with me and that I have to do it...I obviously am not going to. What do I do? Do I give him the freedom he so desperately wants or try to hold onto something I want so badly?
