Go Now!!
Solid movie with just pure character interplay to entertain, lost art.
Reading a lot of the reaction to this movie, and no one has mentioned that the movie turns to black and the song Go Now is cued up. This happens immediately after she drops his hand.
I think it is possible that the playing of that song (remember she asks for Moody Blues at the party).. is being played at the party and she either walks out of the party or is symbolic of the direction of her last phase of her life, in that she won't be that rock that holds her husband in place, with the revelations of the past week.
A lot of films/shows, use that fade to black with the music playing as a contemplation of the ending and Go Now is a song that is pretty self evident... You better go Now..... It's time we say .... Goodbye...
I think she may end up leaving him in the end
