Freeloader is unwilling to put much effort into the care of his or her partner in a romantic relationship. He or she does only what comes naturally and expects only what comes naturally. It's like a person who tries to live in a house without paying rent or doing anything to improve it unless the person is in the mood to do so.

Renter is willing to provide limited care as long as it's in his or her best interest. The romantic relationship is considered tentative, so the care is viewed as short-term. It's like a person who rents a house and is willing to stay as long as the conditions seem fair, or until he or she finds something better. The person is willing to pay reasonable rent and keep the house clean but is not willing to make repairs or improvements. It's the landlord's job to keep the place attractive enough for the renter to stay and continue paying rent.

Buyer is willing to demonstrate an extraordinary sense of care by making permanent changes in his or her own behavior and lifestyle to make the romantic relationship mutually fulfilling. Solutions to problems are long-term solutions and must work well for both partners because the romantic relationship is viewed as exclusive and permanent. It's like a person who buys a house for life with a willingness to make repairs that accomodate changing needs, painting the walls, installing new carper, replacing the roof, and even doinf some remodeling so that it can be comfortable and useful.

Unmarried cohabitation can last years. They do not have any expectations about each other, or the relationship. They both only do what they want to do. They are only responsible to themselves. They see nothing wrong with independent behavior, because they are unattached. If they don't want to do something, they don't. Since there are no expectations for extraordinary care from each other, this agreement can go on for quite awhile. Plus, when it does come to an end, there are usually no lingering regrets on either side. They "move on" carrying no guilt or remorse.
