My wife states that it's "my fault". Is this true?

My wife approached me and said, “honey, since I now have some wrinkles in my face, do you still love me”? I told her that i love each and every wrinkle in her face. She replied, “that’s good, since each wrinkle was my-fault!” I was stunned at her comment. Question: How could my wife believe that her wrinkles were caused by me? Anyone face a similar situation?
