Oh, leave fandom out of it: we hate it when women are portrayed as not good enough because so much of our culture tells us it's true.

When the guy thinks it, it's usually because there's that element in canon, wether stated or implied. It indicates admiration and respect, and, frankly, we want someone to feel that way about us. However, there's never the feeling that he actually ISN'T good enough for her(even if he isn't) because it's made clear that his affection and commitment makes up for it

*nods* Well put.

It goes along with the guy who's so blatant in how much he adores the girl without realizing that he shows it.

That is always awesome.
