10. Sudden need of privacy.
If your man didn’t have restrictions over his phone for the past years that you have lived with him but suddenly shouts at you when you pick his phone and start going through it, something fishy is going on.
A cheating man will always carry their phone and even when need be take it to the bathroom with him, others will have their phone lock pattern and passwords changed that even if they place it on their wives’ pillow, nobody will have an interest on it since unlocking it will be like waking up a dead person.
