Yes, you are missing something. And I'm sorry that we women are so confounding (seriously).
She doesn't know what she wants. She knows she is not sexually attracted to you right now which logically leads her to think, "well then, maybe I need someone else"...but, I'm pretty certain she's missing the mark.
And, the EAs often lead to PAs because guys aren't to satisfied with hanging out and talking indefinitely. I'm not saying the women don't get turned on (I suppose that's the icing) but it is not the impetus.
