Okay so I've only seen three episodes (the one with that Pepper woman's seminar, and the last two)...
I don't really get how Casey could go from asking Henry to stay in episode 9 to deciding to take that job on the cruise for 6 months, telling him he deserved someone better, and quitting in episode 10.
Is there something about her that I just don't know about? (I mean, besides the fact that she was/is married? There was something about a divorce, right? I don't remember :\) Can someone who has seen more of it fill me in?
