I just read about that. In the book it said the problem is with our perception of love. When we think love we think feelings but as NearertoGod just posted
1 Cor 13: 4-8 love is how you react to someone. The feelings come and go just like in a worldly relationship with someone you love. You can feel not very loving towards your kids or husband but still treat them as if you did. I think we're just responsible for the action part.
