Bright, I'm sorry that he's not responded back. He could very well assume that he doesn't owe you a response. There are some people out there that will ask us to do something and never acknowledged that they received the requested product. They are either too busy to think about acknowledging the person or they just care about getting the item and think that we are okay w/little or no acknowledgement.
We don't know what is going on w/your h or how the wheels in his head are turning, but some do become forgetful along the way. I'm not making excuses for his behavior by any means, but they do have memory loss and that could be something to think about.
Keep in mind that you are expecting him to respond the way that you would or the way he would have a year or so ago. Expectations have a way of disappointing or making us angry. Let it go. It's not worth harboring a bit of anger and allowing it to ruin your week.
But, as I've said before, when you've had enough, you'll know what to do.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
