Anyone that unsure and unable to communicate needs to first discover her voice. She must realize that the foundation of any relationship is honest communication.
If she asks, "What are you looking for in our relationship? A good time? Starting slow and seeing where life takes us? A slam, bam, thank you ma'am romp? A possible long-term relationship that might, if things progress over time, end in a commitment from each of us?" ... then I'd say that's as good a start as any. IF he is serious about her, he'll answer her questions. If he's not all that serious but is perhaps a player, he might answer by saying, "Wow. Those are interesting questions. How would YOU answer them?" If he does that, then you can bet that he's only looking to shape HIS answers to fit into the ones SHE gives rather than giving his honest opinions.
Even if he isn't sure, he should attempt to make some serious connection through those answers. THEN it will be her turn, and she needs to be equally frank, equally honest.
Playing games and waiting and trying to read each other's minds... that has disaster written all over it.
