"There's a difference between not wanting to be here and wanting to leave. I know it has never been the former. I just assumed you were... ready to be done."

Something has changed. He can't quite place it. Rey has certainly changed a lot, and Cassian knows that. Jyn sounds like she's putting the emphasis on the mission, and for the first time in his life, Cassian had put it secondary. He didn't care about it so much as just wanting Jyn back. It's suddenly very important to him for her to know wanting her back is not about the mission.

His voice goes quieter. "I was not asking you back as my wife, for any of the appearances. I know everything about this is horrible. Neither you or Rey deserve it. It is a selfish wish, especially when you have asked for space." He glances at her. "I want to fix this, Jyn. For our sake, for Rey's."

But he still feels like he's making her miserable, which makes him feel terrible about wanting her to come home.
