7. Your partner is not satisfied with the relationship.
In a healthy relationship, both partners trust each other unconditionally and respect each other’s rights to privacy, personal space, and having a life that extends past the time they spend together. But if one of them feels a strong urge to snoop, this might be the reason to seriously question the relationship.
Perhaps your partner just isn’t sure that you’re heading in the right direction. Or perhaps they haven’t decided yet if they want to be with you or not. Either way, snooping might point out that you and your partner have completely different values, and you should talk about them as soon as possible.
