I just can't imagine a woman saying, "yeah, he's going to rape my daughter, but I really love him!"

You have a very limited imagination and limited experience in moving outside middle our upper class social circles or you are being dishonest. Go out and meet some young people in your nearest underclass neighbourhood. Or if that is too scary read up on the sociology papers on such communities.

Even outside of that, women find dark triad traits sexually attractive in men. Getting away with violence is also sexy. Now pause to consider in addition to thins things like Stockholm syndrome and do the math.

Also to add mere anecdotal evidence a good friend of mine in primary school was routinely beaten up by the trashy boyfriends his mother dragged home so I have very little patience for "oh noble mothers never make bad decisions for their kids in order to follow their romantic or sexual preferences!" sacredness signalling.
