Obviously this is just a paraphrase; the details of each story vary. But the common thread among them, and the thing that I found so interesting, was that the woman's love grew gradually, over months, often started as complete indifference. It amazed me that a woman could end up being so in love with a man that, initially, she wouldn't have seriously considered dating.
In fact, I was so surprised by this that I initially doubted the truth of the stories. I speculated that the women writing to me were subject to some kind of wishful thinking or tunnel-vision, by which they focused only on the good in their boyfriend rather than the advantages of other men. But this really couldn't explain the phenomenon. A woman couldn't wishfully think herself into a degree of love so strong that she would feel compelled to write me for help. I eventually realized that these women were being genuine, and I was forced to admit that there was a uniquely feminine mechanism at work.
By now most of you have probably recognized the important point for women, which is implicit in my astonishment: men do not fall in love gradually, and they do not find themselves suddenly falling for women in whom they weren't initially interested. I was surprised because I had wrongly assumed that women work the same way as men in this respect. But this is not the case.
