"I'm the kind that uses people. I don't want to use you. Ever. Don't let me. Not you." (1.4.116)

Quote #2
But she knew when she pronounced the "yes" that she had waited for this and that she would shatter it if she were too happy. (1.6.101)
We don't get a lot of insight into Katie's feelings for Keating, but here we get to go beneath her normally calm demeanor and see just how nervous she is in regards to Keating. She's scared to show too much emotion, lest she "shatter" or ruin things.
Quote #3
There were moments when something rose within him, not a thought nor a feeling, but a wave of some physical violence, and then he wanted to stop, to lean back, to feel the reality of his person heightened by the frame of steel that rose dimly about the bright, outstanding existence of his body as its center. (1.11.129)
This book deals with a lot of different kinds of love, and one of the most profound is Roark's love for his work. The diction and imagery here is very physical, as if Roark's work is a spiritual—as well as something of a sexual—experience.
