Always speak as much truthfullness as possible... until you reach a point where the truth might hurt or insult or otherwise make her unhappy angry etc.....after that point... keep your big mouth shut. Anything you say will be held against you FOREVER and you will never live it down. The things you say will be repeated to her family and friends and your family EVENTUALLY also. Keep that in mind when your big mouth is telling it all. Does this policy work? We are married 19 years so far. This strategy works best when you also have a policy of not doing bad things in the first place so you are not faced with those difficult decisions repeatedly.
