Yes her husband was having an affair with the bitch that gets everyone killed by going into an un-mapped dangerous cave.
I hear the US version cuts the ending short so it seems like she gets out (america has to always have a happy ending? :p) but in the original version that I saw in the cinema it goes back to her in the cave and shes just imagined/dreamt it, and she remains stuck lost in the cave with weird mutant fuckers that will shortly find her.
Also, search can be a good tool ;)
