Spaceid--you love him and want to be with him. He's probably afraid of a commitment, but has a lovely relationship with you which is fulfilling in his life. Why not let things proceed with the understanding that he can't make more of a commitment at this time, but you both enjoy each other and what you have together? If you are willing to accept this for now, while he figures out in what direction he's going and what's important to him, what is the harm in that? You will either grow closer together and be inseparable or time will draw you apart, when it won't be so much of an issue with you, to be separate from him. I think there still might be a win-win for you both here.
