Item A Alex and Taylor are discussing their 12-year relationship. Alex says: "Looking around at other couples we know, I feel we have got a really good deal. I do the home maintenance, while you manage the finances and organising. It works out to a great balance." Taylor says: "Exactly, it represents a fair trade.

Honestly, I do not think I could ever find a better partner." Using your knowledge of psychological theories of romantic relationships, explain the remarks made by Alex and Taylor.
