DEAR ABBY: Please answer a question for me. Why do we fall in love with people who we absolutely, positively cannot have? -- HEARTBROKEN IN INDIANAPOLIS
DEAR HEARTBROKEN: You have asked a question for which there is more than one answer. Some people do it because they don't recognize the warning signs quickly enough to back off before becoming enmeshed. Others can't resist a challenge. And still others do it because -- believe it or not -- it's less threatening than falling in love with someone we absolutely, positively CAN have.
