Thank you, Calif Jim. Yes, this is indirect enough, but, unfortunately, the meaning is different. In my scenario, the girl in the above sentence met me at the bar, say, an hour after the concert, and was surprised to see me. So she asked me what my aftertheconcert plans had been. I said, "I was going to meet my girlfriend, go to her place and [let's say] have sex. But she didn't show up, so I'm here instead."
In your interpretation of that sentence, it seems like the girl at the bar is asking me about my plans so that we could go to HER place and have sex.
But, as you said, the perfect form of be going to sounded kind of weird to me, so I decided to ask that question.
I appreciate your help.
