For one woman on Reddit, placing a tracking device in her husband's car seemed like a perfectly reasonable step - but some have accused her of going too far and invading his privacy.
Sharing her story anonymously, the woman explained she first became suspicious of her spouse when he started coming home much later than usual and would leave the house in the middle of the night.
