C'mon, get real.
Love is a verb.
You love or you don't. We spend entirely too much time these days analyzing and re-analyzing our feelings of love. If my concept of love depends on whether I feel in love at the moment, I'll be constantly disappointed. On the other hand, if I come to view love not as something I feel but something I do , I then can take full responsibility for whether I love you, and I don't need any response from you. I love you because that's what I do.
