Let her leave

Mary quietly gets out of bed and makes her way to the bathroom. You don't hear any tinkling but, a few minutes later, she flushes the toilet. Oh! She was pushing out your surprise deposit.

Mary returns to get dressed and gather up her things. You barely make eye contact with her as she goes about her business and prepares to begin the walk of shame back to her apartment. You suddenly start to wonder if you'll ever see her again. I mean, of course you'll see her again at work... which may now be incredibly awkward... but maybe you'll never see her naked again.

"Are we still on for next week?" you ask, sounding as confident as you can manage.

"Listen..." she replies. Here we go. "We had some fun, and you managed to trick me into having anal with you, but I don't see a future for us. You're not the man I thought you were. You just... kind of... don't measure up."

Right. It's kind of hard to argue with that. You've disappointed another woman, and now she's walking out of your home and probably out of your life for good.
