What is it called when someone leaves and comes back repeatedly?

This is chronic mental disorder better known as “Obsessive-Compulsive Disorder“. Obsessions are intrusive, irrational thoughts that keep popping up in a person’s mind. Compulsions usually involve repetitive rituals. Treatment for this mental illness requires care from a licensed professional such as a Psychiatrist. I think this is something that MFOYA should look into. One day MFOYA says “Adios” after writing some irrational thought and then compulsively returns a day or two later. I do think MFOYA has some real mental problems.
