I have many many times. He claims that he thinks of me as dark haired, which I find really really hard to believe. Then he tries to tell me that he loves me and only me.

The damage is already done though. He never should have said that to me, and I really wish I had responded back with "well my preference is dark hair and blue eyes" (when he has dark hair and brown eyes), and that means you'll never measure up to my ideal. Which is exactly how he's made me feel.
