Buyers, Renters & Freeloaders: Transform Short-Term Romance into Lasting Love - Relationship Advice for Modern Dating & Marriage" （注：原书中文名应为《买家、租客与搭便车者：将转门式恋情转变为持久爱情》，但根据您的要求已全部使用英文，并增加了使用场景说明）

Willard F. Harley, Jr. is the highly successful author of many books on marriage, including the best-selling His Needs, Her Needs. In his latest book, Buyers, Renters, and Freeloaders, he turns his attention for the first time to singles who are tired of revolving-door romances and are looking for a lasting, meaningful relationship. The key to starting a successful, lifelong relationship, according to Dr. Harley, lies in discovering whether you (and your partner) are Freeloaders, Renters, or Buyers. Much like freeloading roommates who won't pay their fair share, relationship freeloaders are unwilling to put much effort into caring for someone. Renters are people who view a relationship as tentative and are only willing to provide care as long as terms are fair or until they find something better. The ideal partner, a Buyer, is someone who regards a relationship as he or she does a home-permanent and exclusive. Buyers, Renters, and Freeloaders shows readers how to measure their Romantic Relationship Attitude and offers practical advice for transforming Freeloaders and Renters into fully committed Buyers. It also includes a Personal History Questionnaire to help readers better understand themselves and their partner and Four Guidelines for Successful Negotiation to assist couples in maintaining Buyer behavior. Together these tools will help singles create a satisfying, exclusive, and permanent romantic union destined to last a lifetime.
