Take it from one who knows, one week isn't even close to knowing if she's "the one"...NOT...EVEN...CLOSE. She looks good to you, she treats you right, you're thinking about her even now while you're reading my response (FOCUS, MAN, FOCUS!). That's lust, my friend. Nothing wrong at all with it, just acknowledge the fact and its definition. Lust gets things started. Lust propels guys into action. That's what it's meant to do. Let this phase play itself out, not getting overly infatuated beyond all reason, and maybe she is the one. Maybe. The only thing you really know about her is that she looks great waking up beside you. That's a start!
