It's expensive to live apart. First of all, I know in Japan, a lot of times when a man is transferred to another city, they're given a dorm room, the company has the dorm and they can live there. In America, that's not necessarily the case. I'm sure that sometimes the companies will pay for the housing of the employees like transfer, but it's not necessarily so. But apart from housing cost, there are so many additional expenses such as telephone calls, long-distance telephone calls.
Transportation is another.
The partners probably have to fly somewhere in order to see each other. In addition, there just the general expenses occured in maintaining two households. But these people are doing it for their career. They are hoping the cost will pay off into job advancement. Something that's very healthful to couples in the United States who are attempting to live apart is E-mail.
