A new study finds that couples lie to each other an average of three times a week, using deception to maintain happy relationships.  According to a report from ABC news, researchers say the while lies are harmless because the motives behind them are not usually bad.  The study examined how often people expressed affection toward their partner even when they were not genuinely feeling it.  They call that deceptive affection.   That includfed anything from complimenting your guy's haircut when you actually think it's horrible to kissing him goodbye even when you are mad at him.  The most dominant motives for this type of deception were to avoid conflict, negative feelings, and hurting the partner.  Researchers say the deception in the form of little white lies in order to help to maintain relationships is harmless, but when it comes to the big bad lies, like covering up an affair, that will do more harm than good.
