My husband is lying. The minute he came home with alcohol on his breath and unable to look me in the eyes I knew it. We used to be in love–the intense ‘I can’t be without you for a second’ kind. Where it hurts deep to be apart. But now, we’re the couple that keep secrets from each other. We hide the truth. He thought I wouldn’t find out.

He’s more secretive and also… I can’t quite put my finger on it. They were so close, is this Gale coming to terms with her death?
