In Her Own House?
There is something about cheating on your significant other that completely destroys all of the trust you both once had in one another. Once infidelity comes into a relationship, it can make people second guess every single person’s intentions in their partner’s life… But until something like this happens, you don’t necessarily feel the need to be protective.
When this woman went to be in her own home and left her husband and their friend downstairs, she probably didn’t ever give it thought that something like this might happen… It is plain to see that she clearly trusted her husband and her friend. The fact that this happened whilst she was meant to be asleep upstairs makes everything worse.
