Not What She Was Hoping For

So, I'd been dating this woman for a while, and we hadn't seen each other for a few weeks. We finally get together at her place, and I could tell something was up -- she wasn't all over me as usual, and that had my Spider Sense going off. We start talking about work or music or some bullshit, and, out of the blue, she blurts out:

"I have a new boyfriend."

Now, the response here is key. You don't want to appear too hurt (I wasn't) or too uncaring (I was), so you must play it carefully. Knowing this, I replied:

"Good for you! Who's the lucky guy?"

To say she was taken aback would be an understatement. This is not the reply she was hoping for. She stuttered for a second, then babbled out some response along the lines of, "he's really nice, we're in love," blah blah blah.

She's lucky, though. Here were the others that flashed through my mind:

"We're not having sex tonight, are we?"
"I'm glad I didn't pay for dinner"
"I hope you don't mean me"
"Probably a smart move on your part"
"Is he using his whole ass?"
"I would like another beer, thanks!"
