Modern couples often dream of finding their true love, getting married or making a commitment, and then they will start their family. Life does not always work out that way, but finding someone with the same dreams might change how a couple is willing to proceed with their lives. They could decide that creating a future together does not necessarily mean they are emotionally attached to each other. For many centuries, couples without love or affection between them managed it.
Dreams of the future are often about being in a committed relationship, working towards a better life through a career, and starting a family is also a large part of it for most people. Those unable to find the love of their life do not need to give up their dreams, but they might find changing them is a necessity. Finding someone they respect could be the only emotional commitment they need to make to get what they want.
It could seem as if this type of compromise is too much to expect from a partner, yet it was the norm in many societies for a very long time. Couples married and had families to increase the the wealth or stability of their birth families, or their marriage was a way to settle a local dispute. Either way, they managed to build an entire life together as a team. Modern couples do have more freedom, but applying it is not always easy.
Making a lifetime commitment to another person should come with respect for the future partner. Without that component, the relationship will be more likely to fail. The ability to work together for common goals is also necessary, and these two factors could eventually lead the couple to love or at least a feeling of affection for each other.
