#7: Desdemona & Othello
Probably the couple with the worst communication skills in the entire history of literature. While their demise is not solely of their own making, the task of manipulating them (particularly Othello) is made real easy by the fact that neither seem to have heard of a direct question before. These people act like a romantic partner is an object that can only be observed from afar, and explanations about their behavior must be extrapolated. JUST TALK.
Because Othello doesn't know how to say, "I am upset," he is driven to smother her with a pillow instead. A lesson for us all, here. Don't just leave texts on read: communicate, or you might end up suffocating someone you love.
