How do you decide if you should tell your wife that you cheated?

ANSWER:

Well right now you are really on a hot seat. God knows why you cheated, and do you think she deserve it from you especially now that its almost holiday? If she knew already and she hasn't said anything, you better put your act together and go to her. It needs to come to you even if you think she knew. And one thing you must not say, is don't use this stupid Words most married men use to their wife, " I'm sorry I wasn't thinking." or " Were only friends." and the lame of them all, " I didn't know it will go that way."
