(view spoiler)[I’m a little confused about the ending. When Beatrice is talking to Martha for the last time, did Martha confess that she was in love with Beatrice or just that she wasn’t in love with Jim? (hide spoiler)]
Martha wasn't in love with either. Martha was helping Bea because she felt indebted to Bea. Bea had, unknowingly, saved Martha's life that night of the dance/snowstorm, when Martha was attempting suicide.
