Question on God's creation of romantic love?

Please tell me God created falling in love with someone to mean falling in love with the person for who they are/their personality. Some people claim falling in love is simply a chemical reaction/attraction between the chemicals in 2 bodies. If this is the case, love doesn't seem so special anymore. I honestly don't think God would create something as special as romantic love just to mean an attraction of bodily chemicals between 2 people. Please tell me God created romantic love to mean more than this-to love a person for who they are (to find a deep emotional connection to someone) rather than simply a chemical attraction between chemicals in the body.
