Unfortunately, yes. There are countless women in relationships with abusive men, who mistreat them sometimes up to and including repeated rape.
Ah...yes. I worked with a shelter for battered women and saw this as well. I was thinking more along the lines of a stranger rape, where there is no prior relationship between the two, but where the woman later falls in love with the rapist. I haven't seen that particular scenario in real life, but I guess it has probably happened in the past.
I agree with the "ugh" factor on your second point as well. I wouldn't censor it, but I share your sentiment on how well it works (i.e. not at all).
