You need to work together to preserve the relationship, if that's what you both want. A relationship that's only physical is not likely to last, and statistically 60% of relationships fail. It's up to both of you how long the relationship will last. You need to consider the other person's feelings and act unselfishly towards one another. You need to care, and it's a two-way street. If you're young and inexperienced, this may be a disadvantage, because you may not know what to do when a conflict or disagreement arises within the relationship. If both of you have had previous relationships, they may help you to know what to do if anything goes wrong. When the "newness" wears off and you understand one another better, and you are willing to learn and understand more about one another, you will learn where the relationship is going, whether it should end or continue.
