Love is a necessary prerequisite to fulfill your moral obligation of extending your family line. Love is a function of hormone oxytocin. Oxytocin is a product of activities that include, but not limited to, eye contact, hand-holding, sharing an emotional experience, hugging, dancing, cuddling, and sex. Using these techniques, one can develop love to almost any human being. People, who clam that they can't find love or can't maintain a relationship, simply do it wrong or do not try hard enough.
