If you’re a dude and you’ve hit the point in your several-night stand relationship where she is pressing for more or simply wondering why your actions don’t match the words, the answer is to not bury your head in the sand, call her a psycho, or act aghast. It’s time to re-evaluate what you want, restate your goals openly and transparently, and move on if they don’t line up. Whatever you do, don’t keep playing a role you never intended to truly inhabit. That is an age-old dating concept women have been fielding for years: Bullshit.
