I'm in Love with My Best Friend

Hi. So, I have been best friends with this boy for about two years now and we have had feelings for each through it all. Well... he had feelings for me first. Which I then also developed after about a month of really getting to know him. To try and keep this somewhat short, (though it probably wont be, sorry about that), I will just say that it has become a bit complicated. Now, after already breaking up with him once, and attempting to get over him, I find myself in a bit of a mess. He has finally tried getting over me as well. Which includes him getting involved with another girl. Another, dramatic, underclassman, kind of girl. And of course I felt jealous and of course I tried my best to deny it because I care about him so much and I just want him to be happy. But I want him to be happy with me. And this is all very hard because I have commitment issues. But I want to try. And I want to try with this boy. With my closest fiend. He drives me crazy, we bicker a lot, I yearn for adventure while he is content without it, I am open minded while his is often closed. And yet he is always on my mind. He is the one I miss when I'm cold and alone at night. I am very sure he isn't totally over me yet either. I need some advice: Am I crazy or could this actually mean something more? Should I ask him out and try at least one last time? Should I fight for this?
