Just remember that she fears losing you... for HER.
You don't necessarily have to milk this out; keep her walking on eggshells, or manipulate it to your agenda... and probably shouldn't, 'cause it's garbage (had it done a few times before, so I know how it feels), but the position itself is a good one... just like any kind of uncertainty or unpredictability, and being in "control". It's not necessarily "fun" or "right", but that doesn't matter in the attraction game. And chicks prefer the submissive, "chase", prize / catch mode anyway. There is a lot of truth in the saying, "he who cares the least yields the most power", although that doesn't mean acting like a jackass, and not giving a ****.
You never want to lay all your cards on the table, and should maintain a challenge with the prize mindset intact, so I wouldn't necessarily say you WON'T end things, but maybe tell her to chill; see how things go... and that's reality anyway. Nothing is guaranteed. She'll still be in pursuit mode, and try to live up to your standards. Otherwise, like Player said, they'll inevitably start acting up, and possibly even turn it against YOU.
****'s real... people love having power, and will use it to their agenda - after conniving it out of you. Had that happen, too - after "reassuring", focusing on them, etc. Especially if they were the wounded bird types. Or just obtaining power in general, and knowing they "have" you. Attraction depleted. They should be a little uncertain, but not obsessive or panicky... that's a **** thing to do anyway. We're all people.
But, don't trust (or assume) that people are genuine, won't try controlling YOU (if you let them), aren't acting out of selfishness or emotion, etc.
