Baffled

I'm completely baffled by this one. He insists that he wants me in his life and that he misses me. But he also admits, after 5 months of asking why isn't he letting his gaurd down, that he has emotional baggage. He's been hurt in the past, and now has fear of being hurt or let down. His personality type and his every day life say he's more concerned about being perfect on the job than he is anything else. He knows he can't do the thing a boyfriend is supposed to do so he can't make a committment, his conscious won't let him because he won't do a good job at it. He also freely admits that he is a workaholic, if you hear him talk about it its almost like an addict talking about drugs. He know's theres something askew with working at 1130 at night but still does it. On one note it says that he is committed to doing a good job and getting things done. But it also smells a lot like obsession. I don't know how to deal with this one because work is his other woman.
He would be ideal for me with this one exception hanging over our heads. So how do I deal? He makes time for 1 hobby that he's been loyal to since his last break up. A regular day consists of work from 9-6 or 7 hobby from 7-all hours of the night. This is on a good night to break up the monotany or because the boss tells him he's been working too much. Mind you he's on a Salary. He does this on a regular basis with an occasional dinner with the employees-ers. Then if he's not doing that he is in the office until the work is done. He let me down on a really special planned occasion because of work. He worked until 4 am to get something done so he could come. Needless to say it wasn't possible so he didn't accomplish it and an hour before he was supposed to be on the road (9am) he was still in bed and went to go back in to finish the work. I say leave this one be because he's not ready. But I also don't think he's worth missing out on. These are good qualities that are rare in black men these days. However over the top I have to settle for the dissapointment, lack of communication, and quality time. He insists that he's working on it and this relationship has to be on his terms. He doesn't want me to leave but he understands if I want to. ( As if this has been done to him before and there is nothing he can do about it.
