Just think about all the leading men. One of the appeals of these men is that they make women feel safe and protected. The op mentioned Romeo and Juliet, can't get much more dysfunctial than that! Or beauty and the beast with their love as old as time ; he held her hostage!!! Its over the top romance that like the op said, appeals to young girls and their dreams of meeting their prince charming. Doesn't mean they don't want to kick butt too. Both stories can and do appeal to them.
