"My advice (to patients) is always that you need to talk more with your partner and not less," psychiatrist Julie Holland told CNN.

Holland warned that going through your boyfriend's private information puts your relationship at risk. "You're not necessarily going to find what you're looking for, but you're certainly opening a can of worms in terms of trust and intimacy issues," she said. 

Psychotherapist Michele Paiva told Bustle that people who go through their boyfriend's texts are in need of validation. "Snooping means you lack trust in yourself," she said. "People will say that it is the other person that they do not trust, but in snooping, we are actually feeling like we are not enough."
