Fictional Emotional Undisciplined Expression

In the latest Batman installment, the character of Rachel Dawes says to Bruce Wayne, "Don't make me your only hope for a normal life." I thought that was just a bit on the odd side. It seemed like she really wanted to say something else (and maybe meant something else), but said that instead. I think she should have stuck to something like, "I really don't want to date you." I mean we all have "conflicting" feelings now and again, but does every feeling need a voice? If you were to voice all of your feelings all the time to a person, then every time they were in conflict you would confuse the person you were speaking to. Ask yourself this, "do I really want to confuse the people I care about?"
