i think your girl friends are abnormal--not that abnormal is bad, just not typical. very abnormal.
i think what guys resent the most is that women are much more sneaky and underhanded about their attempts to change guys. guys will pretty much always tell their ladyfriends how they want them to change flat-out. girls will use their moods, sex, tears (ugh) or even outright deception to change a guy.
even beyond the blatant/subtle thing, i think girls definitely try to change guys a lot more than vice versa. girls just have more tweaky/fixing attitudes in general and especially when they enter a relationship; most guys don't enter into a relationship with a short-skirted hot girl thinking "i'm going to change that short skirt shit", but many girls do enter a relationship while gauging, "okay, i think i'll be able to change X...possibly Y...not Z, can i deal with Z? yeah, i can. okay, Y will be a project, but i think..."
and again this stuff isn't all necessarily bad. i think you can boil it down to the fact that women simply think about the relationship they're in the process of entering more than guys do. thinking more is ALWAYS better. additionally, dominating someone through commands isn't necessarily a lot better than controlling them through emotional manipulation, weepiness, and deception, is it? so i'm not saying "girls suck because of these things". but those things, i believe, ARE generally true for most girls.
