Uncle_DaveO, you may be right, I may not be positing from a statistically significant population in numbers but in my not inconsiderable number of yours FAR too many of these kind of events have occured, so while it may not be most(and I do not think I said or implied that) the number I have encountered (and used my waterproof shoulder to comfort) is way too high to say it is insignificant.
If you re-read my post you will find I was not quantifying the occurance but wondering how this behaviour, when it does occur, factored into "survival" characteristics" in a positive way, even if only a relatively small number of women do it it would seem to me to be a negative survival trait. Maybe it is "learned behaviour" in the same way that abuse (both giving and receiving, often where the recipient becomes the abuser in later life) seems to perpetuate down through generations
