Gotcha!
There is nothing more upsetting than to become aware that someone in your life has been deceitful to you. Whether it is your romantic partner, a friend, or even a family member, no one wants to ever feel betrayed by the people they love.
Even though this would have been an incredibly awkward thing to have done, there is something extremely powerful about it. As much as it would have been painful for this woman to read out these messages, it might have felt like she finally felt in control of things again.
