If you're both working from home, and with nowhere to go out to in the evenings, there's a chance you might start to get on each other's nerves. Perhaps it's happening already.

This is normal, particularly given the increased stress we're all feeling right now. But since we could be in this predicament for a while yet, it's worth taking steps to ensure we get through this period with our relationships intact. We might even be able to come out stronger.

American psychology researcher John Gottman proposed certain behaviours, or the "Four Horsemen of the Apocalypse", lead to the dissolution of romantic relationships.

The first horseman is criticism. This behaviour is defined as an attack on your partner's character, as distinct from offering a critique or voicing a specific complaint.

Particularly at a time like this, you might be keeping track of your partner's flaws but not saying anything so as to avoid conflict. But bottled up, anger and frustration will turn to resentment, which you may express by criticising your partner.

Psychologists explain criticism includes inflexible "always" and "never" statements such as "you always have to have the last word" or "you never listen".

The second horseman is contempt. This behaviour is defined as an insult to your partner. People might do this verbally using sarcasm, or simply by rolling their eyes.

An example is when your partner is talking to you and you say "here we go again" without mindfully listening to what they are trying to say.

The third horseman is defensiveness. This behaviour is defined as a counterattack, most often in response to perceived criticism. People use this as a strategy to protect themselves when they are feeling victimised. They assign their partner responsibility for causing them pain.

You might be exhibiting defensiveness if you're constantly feeling criticised, misunderstood and blamed by your partner without cause, and have an "I am right and they are wrong" attitude.

The fourth horseman is stonewalling. This behaviour is defined by elaborate manoeuvres to avoid interacting with a partner. People who stonewall will often stop communicating with their partner, with the exception of negative non-verbal gestures.

People deal with stressful situations by rationalising the best way to protect themselves. This might mean pushing your partner away using the four horsemen.

Gottman estimated these behaviours are 90% accurate in predicting relationship dissolution if not addressed. In his research, couples exhibiting all four horsemen who divorced did so on average 5.6 years after marriage.

A lack of relationship skills - that's not being open to finding solutions and not admitting any fault for relationship breakdown - is another key contributor to relationship dissolution. So it's important to do your best to work on your relationship at this time.

As well as making an effort to avoid the four horsemen, here are some other tips for how you and your partner can emerge from this crisis with your relationship intact - if not improved:
