Heh, it's her taste in men and the way she spoils them that's the problem. I suppose stressing the men in her life out will weed out the moochers or useless ones, but play too many games and no one will want to play with you.
(if you really must run romantic partners through the gauntlet, which I think is antithetical to a good relationship unless you're really having bad luck with dating, maybe the ones that make it through are worth considering? Or they have a huge tolerance for bullshit/discomfort, which can be worrying too)
