OneDay, let me first say, I love that quote by Joseph Campbell
well, he doesn't have to spend Christmas by himself. If he was going to fly the both of you to his brothers, what is stopping him from flying just himself? He can visit with his brother without you, and is just trying to manipulate you with guilt. And if you give in you will most likely from the sounds of it, have a horrible depressing time.
It sucks that you hoped for more this first Christmas than you are heading for, but, maybe you can spend it with your family, or helping at a soup kitchen, or neighbors, or something wonderful and meaningful anyway.
