Dear Sam, My husband and I have been married for 6 years out of those 6 years he has never had a password on his phone there has never been an issue with me going through it no trust issues nothing however I have always had a passcode because the kids share with me. (He's always had access if needed) so he went to the store and left his phone on the couch I pick it up and this is how I discovered that his phone is now locked. I want to address the issue but i dont want to look insecure or like im accusing him of something. How would you approach this issue?
