There are many reasons why relationships fail. Some people will tell you their relationship failed due to infidelity, addiction, lack of attention, abusive behaviors, or severe money problems. And while these are all legitimate reasons for a relationship to fail, I propose that these reasons are just symptoms of the real reason why relationships fail. From my perspective, failed relationships have one thing in common. Relationships fail due to a difference in the desire and ability to create true intimacy. I believe that this is at the foundation of most, if not all, breakups.
