Well, perhaps Smith wasn't absent from his family such a very long time. In Tolkien's essay on SoWM I found this interesting detail:

But it is also necessary that Faery and the World (of men), though in contact, should occupy a different time and space, or occupy them in different modes. Thus though it appears that the Smith can enter Faery more or less at will (being specially favoured), it is evident that it is a land, or world of unknown limits, containing seas and mountains; also it is plain that even during a brief visit (such as one on an evening walk) he can spend a great deal longer in Faery than his absence counts in the world; on his long journeys an absence from home of, say, a week is sufficient for exploration and experiences in Faery equivalent to months or even years
