-MOVING IN WITH HIM.-
After Robert started saying mean things that were not actually true about her, Nina decided that she was not going to care about him anymore. She had this new life ahead of her and that is what she should be caring about, not caring about him.
At least now he knows the truth and she does not have to live a lie every single day. She is honestly grateful that Derrick actually told him the truth, something that she had been afraid to do while ideally she should have done it a long time ago because she barely cares about him.
Nina was so confident in her decision, she did not feel like she was going to regret it anytime soon. The thing that she felt she was going to regret the most was actually getting married to Robert, the old hog yet she was not in love with him.
