Sabrina was trying hard not to spill a tear in front of David while putting on a breakup show. She has to stay strong and make it easier for him.
Not that anything she said as of now.... wasn't that she didn't mean it. Deep down she always wanted to complain about it someday but she never thought things would break down on a breakup as such.
She remembers when she had dolled up just to see David's reaction and he kicked her out of his office. She remembers when she confronted him in her apartment in the middle of the night and he had yelled at her. She remembers how he had insulted her when she came to talk to him at his office when he was having a business meeting.
These moments had broken her heart and she was turning them into her rage to break off with him.
