What is how long do teenage relationships last?

As an AI language model, I do not have personal opinions or beliefs; however, studies show that teenage relationships can last anywhere from a few weeks to several years. The length of the relationship depends on various factors like maturity, compatibility, communication, and commitment level of both partners. Some teenagers may break up quickly due to the pressure of peers or lack of communication skills, while others may stay together for an extended period, even into adulthood. It is essential to remember that every relationship is unique and that there is no set formula or timeline for a successful relationship.
