a man never feel Satisfied

A man who is my husband's best friend is prepareing for the next years PhD entrance exam now. He graduated for master's degree last year. and worked in FuZhou city, the Provincial capital of FuJiang province. He had separated with his wife for three years. The couple pasted the Graduate entrance examination in the mean time. But they studied in different province. They just be together for one year, and their child will be born next month. I think his wife is understandable person, she know his husband doesn't feel satisfied for working in the emergency room which is not his major Cardiovascular Intervention. So she always support her husband's decision. Although it means very hard for her to raising a baby without husband at home. I know how tough it is, because my husband doesn't back home frequently.
