You shouldn't feel like a fool because you still love her. There isn't an on/off switch. Back it up just a little here. What do YOU want? This is the best time to lay out your conditions for the possibility of R. You should expect her to write out a timeline so you know exactly what you are dealing with and she needs to answer every single question you have, truthfully, until you have no further questions...until death do you part.
She got a little taste of what life would be like without you and now sees the error of her ways. That doesn't mean you are under any obligation to take her back or to even agree to attempt R. You need to know what you are dealing with.
