Example :

John Cena and Nikki Bella

John spent 5 or 7 years with Nikki saying he didn't want kids or marriage leading Nikki to chase him hoping one day she would get those things.

So fast forward about 6 years he asked her to marry her, she said yes and later started to feel wierd about it couple months later he says he is open to the idea of having kids again. Now Nikki doesn't like him anymore because the chase is over she got everything she asked for so now it's boring.
