Although being loyal to friends is a big part of what makes it work, there are times when these interpersonal relationships simply break down. The reasons why you may no longer be friends with someone are numerous. Sometimes, it simply comes down to proximity. If your friend no longer lives close to you, then it might be that you start to feel less connected to one another, especially if you no longer keep in touch. That said, some friendships will cease because of something altogether more abrupt. This could be a falling out over an issue that cannot be patched up for whatever reason. Although there is usually some mental anguish that is associated with friendship breakdown, it is important to remember that people can choose who they want to be friends with and there should never be a sense of obligation on either party. It is a part of life that not all friendships will be lifelong. However, if you still have a mutual friend with the other party, it is important not to pressurise them to choose between you and to respect them if they wish to carry on being friends with you both.
