Shirley ‘knew’ what she was ‘getting into’ when she married Glen. She knew he was “Special Ops”, could be deployed at any time.
He would go away and there might be no contact until he returned. If he returned.
She had figured out how to manage his absence.
During the time he was there no one else would be in their lives. When he was gone, she would call all her friends, visit relatives, and focus on her job.
She would stay busy so she wouldn’t be sitting there, worried that ‘something’ might happen.
In a way, this ‘vacation’ from Glen made the marriage more precious.
