Whether it is the first encounter, or just a casual meeting in a continuing relationship, people want to look good when they are on a date. They take care to ensure their grooming is perfect, their clothes look good and their appearance is the best it can be. This is an important factor in continuing a relationship, and people understand the need to impress their potential mate. Unfortunately, making a commitment seems to lessen the need for looking good.
People who are in a long term relationship, married or just committed, tend to relax when it comes to their appearance. They often gain weight, stop worrying about every hair being in place and dressing in stylish clothes. It is as if they have met their goal, and they can now be themselves. In the past, this was an accepted way to live, but it is no longer valid. Keeping up appearances in a relationship is more important than ever before.
