She has instant access to sex. At all times. If she has a child with you and relies on housing from you she will NEVER tell you she cheated. Either will the guy she cheated on you with because he wants to have sex with her again.

People think guys cheat more but the truth is girls are much better at keeping secrets. My best friends wife has tried to have sex with me several times. He will never know because I don’t want to upset the relationship he has with his daughters. The other reason I won’t tell him is because it always comes off like the guy initiates it and that is not the case.
