I did not want to stand up for him - I despise his actions as well, but I believe it was an arranged marriage. He proved that he was not worth to be king in his later years at least. But I don't think he is happy where he lives (not that he deserves happiness I should add).
I didn't mean to sound like I was responding to your understanding of an old man in a difficult situation, not at all. And I agree 100% it was an arranged marriage and they both made the best of it in the beginning. No matter what, he brought Spain out of a very difficult period.
He just never knew when to rein that ego of his in and thought he was above the law. The law is now showing him otherwise. It is sad, I'm sure his family misses him as much if not more than he misses them.
