High Quality Content by WIKIPEDIA articles! Obsessive love is a state in which one person feels an overwhelming obsessive desire to possess another person toward whom they feel a strong sexual attraction, with an inability to accept failure or rejection. Although not categorized under any specific mental diagnosis by the DSM IV, the problem is believed by many to be a mental illness that may be related to obsessive-compulsive disorder. Obsessive lovers may feel entirely unable to prevent themselves from extreme behaviors such as stalking, rape, and other acts of violence toward themselves, their target, or others. They may be entirely convinced that their feelings are love, and may reject the idea that their severe obsession is not love.
