Flawed relationship

My second romantic love was Susan. She was extremely pretty, but she was flawed. Her nose had a small bump on it. I loved her flaw; I loved her nose and I told her so. Our first and only disagreement!

I saw her months later in a shop, sporting the most perfect little nose. We spoke, I noticed, I said nothing. I felt nothing too, because in gaining her perfection, she had lost her soul.

Things come in threes. My third and best love has always had a perfect nose. So where is that flaw I require? I'm not telling!
