I respectfully submit that the feelings we have after a month are not "love" but infatuation -- the very real high we feel during the discovery process.

I had an interesting discussion last semester with students in an interpersonal communication class. Students represented such other languages as French, Spanish, Portuguse, Greek and Italian. They said that saying "I love you" in American English has so much weight that they have to avoid it. In their languages, there are many more words for love apparently, that include loving a friend, loving a friend one is dating, loving a child, etc., and these alternative words are less scarey to say because the other person will understand the weight that each of these words carries.

It's too bad that our language is so impoverished when it comes to expressing love.
