Was she unfaithful?

Rating: 8/10 (7 April 2017)

Although there are some forced situations, it is a great movie. Yet, what I find disturbing about this film is the fact that the murdered woman (Liliana Colotto) let her murderer (Gómez) in and her husband (Morales) did not know it. Was she cheating on him? It's perfectly possible that a woman lets an old acquaintance in without her husband being aware of it, but to me, it's more likely that she was being unfaithful.
