Passionate Love
Aren't new relationships great? You know that giddy feeling you get when you first fall in love? If you have intense feelings (positive feelings) toward the other person to the point of really being wrapped up in the other person, you have passionate love. This doesn't have to fade over time, but it often does. It's not realistic to expect this heightened state of emotion and passion to be maintained over a long period of time...but it sure is nice!
