You don’t have to worry about what you keep on your cell phone when you have nothing to hide.
The problem is not that you have your cell phone safely, the problem is that you do it to hide a secret that harms your relationship.
Live intensely with the partner you love, if you are loyal you can be happier.
When you have nothing to hide, you reduce the stress that one day, through carelessness, your secrets will be known.
Being loyal to your partner is the best way to live.
