Some people expect their partner to show them love at all given time but they are not willing to go extra mile to proof their love. No matter how he or she loves you, if you don't show him you're worth the love, he or she would gradually grow cold feet.
I agree, it is a two-way thing. And even getting your partner to respond to your love with his or her ways is recorded in the art of seduction too. It's a chapter that is titled "Give them space to fall --The pursuer is pursued".
It highlights, how the one who was doing the seducing can turned to be wanted, pursued, or even tried to be seduced by the other party.
