Does monogamy resemble addiction?

Recent research suggests the following:

The reward mechanism involved in addiction appears to regulate lifelong social or pair bonds between monogamous mating animals, according to a Center for Behavioral Neuroscience (CBN) study of prairie voles published in the January 19 edition of the Journal of Comparative Neurology. The finding could have implications for understanding the basis of romantic love and disorders of the ability to form social attachments, such as autism and schizophrenia.

In other words, if you are monogamous, your feelings toward your partner bear some resemblances to other addictions.
