Shannon's reasoning involves the sunk-cost fallacy, which refers to the tendency to continue investing in something (in this case, her marriage) because of the resources already invested, even if it's no longer worth it. In other words, Shannon feels that the time and effort she has put into her marriage is a "sunk cost" that she doesn't want to give up, even if it's not making her happy.
