Right, it's a cycle. You'll have leaves, then flowers, the flowers fade and die and then the leaves will die down. Don't throw it away like I did in my younger days! Keep on watering it occasionally, and it will spring back up when the time is right. The plant I have was left by a previous renter 35 years ago, and it's still going strong. I really need to divide it, but have procrastinated. I'm sure my pot is solid roots now.
