ELI5: How come an individual's appearance seems to "change" depending on your feelings towards the said individual?

Eg. When you fall in love with someone, they seem to look prettier/more handsome than how everyone else perceives the individual, and then they return back to "normal" once you're over him/her.

Attraction is more than just finding someone to be physically beautiful.  As your desires in a mate mature the non-physical criteria start to carry more weight.  As you get to know someone deeply you become aware of all of their various qualities in a way that outsiders do not.  Ideally you are very attracted to many of those qualities.
