The correct answer is commuter marriage. Commuter marriage refers to the type of marriage which exists between two people who don't live together. In the case above, the husband lives in another city due to work, whereas his wife and kids live in their old city. However, he still comes to visit them as much as he can, when he is not working.
Josh and Martha are married and lived together until josh's job moved to a different city. Martha stayed behind with the children in their old house. Josh visits as often as he can. Josh and Martha have a commuter marriage.
