Answer: Communication privacy management theory /CPM theory
Explanation:
CPM theory works with how people make decisions about disclosing things that are personal or private to them or how people receive such news.
Private information is only known to the person and others can only be aware of it if the person decides to disclose that information.
This information is maintained and monitored by the individual however a person lose that ability after they have disclose their private information.
When people want to decide if they could share or not share this private information it may create conflicts especially when the information is owned by more that one person such as the private information between married couples .
One person may want to wait before they disclose the private information and the other may feel too excited and ready to to share it such as the pregnancy news in the text above.
