I'm a credit to my gender
We do it all the time because it's a small thing that makes the other person happy.
That is a lot bigger deal than some people might think.
Women are not any more complicated than most men. Men that think they are, are just being obtuse, or maybe even self absorbed.No, maybe that's the difference (and the key).
I've been in a number of long-term live-in relationships though, and that's been my experience even in those relationships - i.e., even dealing with them on a constant, day in day out basis, long after the infatuation of the unknown has passed. It's of course not the same as being married in some important ways though.
EDIT: Do you mean to suggest to me that women, who aren't otherwise, become insufferable or just very demanding when they get married?
