Yeah. It's projecting. At no moment had I thought that she was about to leave him. There's a lot in the movie to prove otherwise. Giving a family heirloom to someone you are about to dump? Come on. Plus, after 4 years she kept so many things from Chuck. It can't be guilt, because you can feel guilty because someone you were going to dump vanishes, but after a year you kind of forget. But holding on to the Grand Cherokee, the towels and remembering what type of milk he liked with his coffee is not something you hold on to out of guilt.
