Norris Moore was leaning on the sofa, propping her face up. Upon hearing Rufus Swallow's words, she responded indifferently, "Probably."
She initiated it, he agreed to it. It was a peaceful break-up. Things didn't get too ugly.
Her relationship with Trenton Smith wasn't meant to last a long time. Breaking up now over a small thing was fairly normal.
When a couple is together, the process invariably involves mutual adjustments. If these adjustments don't happen, the relationship continues. If they are not amicable, sooner or later, a split is inevitable.
She and Trenton Smith probably wouldn't compromise for each other for a lifetime.
She had grown tired of this relationship, and it seems he had grown tired of it too.
Although she still believed that Trenton forcing her to break up through the cold war was a quite tasteless move.
