My first attempt at a story here, please don't judge too harshly.
Reconsidering?
As she sat in her office going over case files all she could think about was Hodges telling her about losing Wendy and for her not to make the same mistake with Vartann.
She feels bad for telling him no, but her past choices in men have always been wrong and she is afraid to just let go and trust him. The image of his face when she said she couldn't move in with him won't leave her memory it broke her heart but she didn't want him to know that. She like him, misses having someone to come home to at night. Although she has tried to be strong, he is slowly breaking her resolve.
She cannot concentrate on her work; he is all she can think about. Maybe she should have told him yes; that she would consider living together. After all he truly seems to care for her and when they made love it was incredible.
She cannot take it anymore; she needs to see him even if just for a moment.
She calls his phone, he doesn't answer. She leaves him a message: Hey, its Catherine can we get together after shift is over? We need to talk.
