I replayed this game many times and found that there is no way to save the wife. At least there should be an ending that we can save both wife and daughter all together.
And , in some paths depend on the decisions you made, the wife and daughter disappeared all together without telling that where they had gone is not a good thing.
This game is very well designed. Feel like a protogonist in a horror movie! COOL
