Advice if a guy keeps flip-flopping?

Anonymous
A guy ALWAYS makes a big gesture, showing his kindness by doing me a favor, but mid-way he backs out, then finally decides to meet his initial obligation.

I would understand if he had just said "No, I can't" from the beginning. I'm just not certain what to make of all his flip-flopping.

For example, after a month-long agreement, he did another one of these last-minute flip-flops; I had to pop around to his office last week, unannounced, to ask him what was going on; he was really sweet, a little defensive, but when his excuse flopped, he explained what a big deal it would be for him to do this thing for me and agreed to work on the task. He had it completed perfectly by that afternoon.

What in the world is up with this guy?
