Who should I choose?

I have been going to school with these two guys named Alan and Danny for almost three years. When we first met, Alan and I immediatly felt a connection and we started dating, only to be broken up by a jealous friend. Not knowing the truth, we always blamed each other. This past year, Alan and I started dating again. He's always made it very clear in his words that he loves me and would do anything for me, yet I never get any time with him. Alan is the popular type, and he always has mobs of people following him around. Whenever he's with his friends and I'm around, I get completely ignored. Whenever I bring it up, he appologizes and says that he wants to spend time with his friends before they leave next year.
Since I have all this free time, I tend to spend it with Danny. Danny is a sweet, funny guy who really WOULD do anything for me, and he's liked me for three years. I find that I can talk to him about anything, but it feels like he is waiting patiently for Alan and I to break up so he can have me for himself. I would be going out with Danny if I wasn't going out with Alan, but I really don't like Danny as more than a friend right now. I love Alan, but he seems insincere. I know Danny would treat me better, but I don't want to wait for Alan to pull himself together.
WHAT SHOULD I DO???
