That's everything what modern marriage today isn't. That's basically a religious view of marriage, which can freely exist, but has no legal binding at all, and whether divorce is ethical or not for one or some religions/"philosophies" is not necessarily universal.
The relevant question is not whether it's legal nor what one's religion has to say on the matter. The question is whether he showed character, and we can evaluate that by whether he lived up to his word and--especially--by how his wife took it.
Regardless, "living up to one's words" means nothing regarding the validity of a statement. I can say 1 + 1 = 1, but then in my private life behave as if it was 2; that does not affect the truth of the former statement.
It's not like some people find age gaps in sexual and romantic relations uncouth, so it's not hard to make the jump as that's what you meant.
No, it's not; sexual assault and harassment are part of working life and/or public offenses, not “private life”.
Edit: Not contesting you, btw; just correcting a misinformation.

I do like that he's still around for the NYT's commenters. They remember everything.
