If there's one thing I've learned, *some* guys (I would say all but I don't want to cause a stir, hehehehe ) have difficulty showing their emotions. They tend to think if they avoid the problem, it'll go away. Or sometimes they think you might not want to talk to them so they just don't talk. I'm sure his intentions are in the right place but he just doesn't know how to show he cares. I'd talk to him about it and see if this is the case.
