How can you tell if you are being played by a guy or if he is just wanting to take it really slow?
* he wants to learn more about you, which means he wants e.g. to discuss things yet undiscussed (or unfinished), or experience situations yet unexperienced with you.
* he wants to digest / think about what he has learned, analyze his feelings, meaning he needs a bit of free time without you.
Since most daters don't stay almost permanently together, the only valid reason for taking it slow is the need to get to know you better. Now if he's a shy or inarticulate guy he may not dare or know how to ask or find out. Then help him, but don't spook him. Or maybe he already suspects what your answer would be.
