The adrenaline rush of arguments can become an addictive hobby for some couples. But that kiss-and-make-up conclusion to a squabble shouldn't be your sole reason for engaging in a shouting session with your partner.

Hayman says: "Arguments become a negative part of a relationship when they are circular, repetitive and destructive.

"Most of all, you're in trouble when you're actually arguing about something else - for example, the row is about leaving the lid off the toothpaste but the real conflict is about the fact you think your partner doesn't love you, respect you or is cheating on you."
