She has to be cheating on him
After closely inspecting the pictures that Sara had obviously tried her hardest to make it look as inconspicuous as possible, David spotted that Sara was not wearing her wedding ring in any of the pictures! Davids cannot believe it, but he knows there could only be one explanation for this…
Sara has to be cheating on him. There are no other explanations for her taking the wedding ring off. With his hands shaking from rage, David sends a thank you to Sara and puts his phone away. This is not something he is going to discuss over the phone, and he will wait to confront her in person.
