Yes, it is true that he was married and that he had his wife in the attic. But, it is also true that, at that time, there was no such thing as divorce, meaning that he had a sick wife, a woman he didn't love, a woman who didn't love him either, and that he had no other way out than to leave her in the attic. But, not locked up, at least, not as a prisoner, because he did take care of her. So, if you have to look at that, you have to put it in the context of the time to then see what could be done, what couldn't be done, what was right and what wasn't. I am referring to the subject of love in his relationship with her, not the relationship between the threasome that they had there at that time.
