Well real love isn't a feeling. It's not something to fall in or out of. 
That's the corruption of the grand idea of love that has happened over the last 50-60 years.   We've been led to believe it's a feeling, an emotion.

But the love Jesus taught was a love of the will, a decision made daily to seek another's greatest good, despite good or lackluster feelings. God often blesses us with "experiences" of warmth but very often he asks us to love anyway!

The 20th century French playwright and mystic Gabrielle Bossis wrote in her prayer journal (entitled "He and I"):   May 30 - Lyon. - "Is it love when my heart beats more quickly when I think of You?" "Yes, it is love. But it's also love when you make an effort to be good for My sake without the slightest pleasurable feeling. Have I ever overburdened you with work? Or taken more than you could give? I measure everything."
It's an insidious thing...seeking the reciprocal feeling as we "pour ourselves into the life around us".
