Reassuring quote from an unexpected source

The following quote is from the movie, "Juno":

Juno MacGuff: "I need to know that it's possible for two people to stay happy together forever."

Mr. MacGuff: "Look, in my opinion the best thing you can do is find a person who loves you for exactly what you are. Good mood, bad mood, ugly, pretty, handsome, what-have-you. The right person is still going to think the sun shines out of [you]. That's the kind of person that's worth sticking with."
