Digital Snooping Destroys More Trust Than It Creates

Checking their phone might give you answers, but it guarantees a new problem. Even if you find nothing, you've just proven that you don't trust your partner -- and if they find out, they won't trust you either. If you find something, you can't confront it without revealing that you snooped. Either way, you lose. If you need to spy, the trust issue already exists -- address it directly instead of digging through someone's private messages.
