Emotional Betrayal

One partner has an extremely close relationship with a person of the opposite sex that transforms from regular friendship to something more. Instead of just hanging around platonically, the partner begins having feelings of attraction for the other person. Generally they begin talking intimately about things they should only be discussing with their significant other. They flirt with the other person, and behave inappropriately. They may withdraw from their partner. Unlike a cyber affair they do see the other person, sometimes having lunches or dinners or even just meeting somewhere for coffee. They behave in a manner that is secretive and hurtful, keeping information from their partner and sneaking off to have private email or phone time with the other person.
