It is an impossibility

The other day I came across this quote by Anne Morrow Lindburgh about love:

“When you love someone you do not love them all the time, in exactly the same way, from moment to moment. It is an impossibility. The only continuity possible, in life as in love, is in growth, in fluidity, in freedom, in the sense that dancers are free, barely touching as they pass, but partners in the same pattern. The only real security is not in owning or possessing, not in demanding or expecting, not in hoping even. Security in a relationship lies neither in looking back to what was in nostalgia, nor forward to what might be in dread or anticipation, but living in the present relationship and accepting it as it is now. One must accept the security of the winged life, of ebb and flow, of intermittency.”

Isn’t that true?
