I had a similar experience! A friend of a friend on Facebook developed a crush on me. We started talking and he started calling me on the phone. He lives across country so we never met, but he was smart and kind of charming on the phone and I was starting to warm up to him. Then one day he asked me what I thought when I first saw HIS picture (he'd fallen for mine originally).
Silly me, I told him the truth - that at first I thought he looked kind of scrawny and intense, but when I heard his voice I REALLY liked him. Well, he never got to the second part of the sentence. Got tremendously insulted and took down his FB page altogether in a depressed snit (and he uses that page professionally!)
Now granted, I should not have used the word scrawny - but at 5'8" and a very slender runner physique, that couldn't have been a surprise to this guy. A person with a healthy sense of self would have been able to laugh at the truth in that part and been pleased that I thought his voice was sexy. But his reaction showed me that I was dealing with a very insecure and unstable person. It scared me, actually.
Your girl was fishing for a compliment to make her feel better about what she KNOWS is her weight issue. Your answer was honest and ultimately sweet -that you really really like her! Maybe you could have worded it better, and maybe you can send her a note explaining yourself better. But the bottom line is, if she's super-insecure, you may be wrong no matter WHAT you do.
