Unless you were extraordinarily immature for your age at 40, I don't see the correlation you're trying to make.
I don't know what you mean. I was 32, a divorced mother of two (ages 4 and 5), and a successful professional (CPA amd computers) when I met my husband. He was 45 at the time. I certainly wan't looking for a daddy-- but finding a man willing to be the father-figure for my girls was wonderful. In fact, I wasn't interested in any man who wasn't willing to fill that role-- my children came first.
But, a 40 year-old childless man dating a 60 year-old woman does seem to me to be reverting to an earlier stage of development-- looking for a mommy/teacher figure.
Yeah, that was a telling remark, wasn't it.
