If you have to snoop through your significant other’s things then you shouldn’t be with that person. It’s as simple as that. If you can’t trust them, then why are you with them?
My friend Gina called me in a tizzy because she found a bar receipt for nearly $100 in her boyfriend’s jeans when he said he was working late. Of course, he shouldn’t have lied to her about where he was, but she also shouldn’t be going through his pockets. He very well could have gone out for drinks with his coworkers after they finished their project to celebrate the completion, but that’s not the point. Her snooping was clearly founded because she doesn’t trust him and he obviously gave her reason not to. They both need to save each other the grief that will occur when she confronts him because then she will end up looking like the bad guy — the untrusting snoop — not him — the untrustworthy liar.
A relationship without trust will not succeed.
