However, I believe that portraying that temptation as a "love triangle" is way off. For example, in a healthy modern marriage, the husband will occasionally look at a hot girl walking by. That doesn't mean that there is a love triangle with him, that girl, and his wife. It just means he's being human. I think playing that glance up until it becomes a huge issue goes against what Tolkien meant.

There's a big difference here; the girl walking by doesn't know the husband and probably doesn't think twice about him unless it's to wish he would stop ogling her. Very different from Eowyn, who had a big emotional investment in Aragorn.

Also, Tolkien's Catholic faith doesn't mean that all of his characters have to behave according to ideal Catholic standards, even his heroes - look at Graham Greene, he was Catholic and wrote about faith extensively, but that didn't prevent his Catholic characters from really going off the rails morality-wise. Being a Catholic novelist doesn't mean that your characters somehow magically behave better. Characters do what they do; the best you can hope for is to be able to write it all down well enough.
