Do you have a password protected smartphone or do you keep it unlocked at all times.
And
Would you let your partner , any status , access your phone messages , contac and other personal data without permission ???
Actually the last question is not possible since all phones can be password-protected. So without permission is then impossible, unless he hacks it one way or another.
Plus if you 'let' your partner access then you allow access which cancels out the 'without permission'.
As for being okay with him accessing my phone messages... I have nothing to hide, but that doesn't mean I want my partner to know everything I talk about with my children, mother, friends.
I doubt anyone knows everything from what their partner thinks, says, discusses with others.
Also doubt anyone would want to know every single thing as that would be a huge flood of information 24/7.
And if someone doesn't trust me, well... not a good relationship.
