El desierto (2013) - www.imdb.com/title/tt2665470/

Plot - In the wake of a catastrophic global disaster that has left the outside world infested with menacing threats, three young survivors—Axel, Jonatan, and Ana—isolate themselves inside a heavily fortified house converted into a concrete bunker. Cut off from reality, they manage their daily survival through strict house rules and private video diaries. However, the claustrophobic confinement completely fractures what was once a harmonious, intense polyamorous love triangle. With Ana and Jonatan now pairing off as exclusive lovers, a bitter atmosphere of unrequited desire and jealousy forms under the roof. The toxic domestic friction reaches a volatile breaking point when, following a reckless dare, they capture a living specimen from the outside and bring it into their home, systematically dismantling their fragile psychological walls.

Hard to work out the cheating scenario someone Spanish may work it out

imo you should verify there is cheating before posting this. Based on the user reviews there doesn't seem to be any cheating.
