Your instincts are really pointing you to something important. I believe that if one says never, ever, ever *blank* will happen or I will never, ever feel *blah* and *blah*, well that is just inviting the universe to mess things up. What we fear the most, what we won't face directly, well that invariably bites us on teh ass. This is a good reason to put the brakes on this particular possibility, as well as what others have said about her vulnerability right now.
