Aren't those beautiful words?
They ARE. But words are LITERALLY hot air.
If you really love someone - SHOW IT!
How?
Great question.
The answer is the same as the answer to the question of "What type of boy/girl should I marry?" "What should I do for a living?" "What flavor of Ice Cream should I buy?" [Huge question!] Answer - individual. What I looked for in a wife [a girl who was willing to marry someone out-of-the-box-off-the-wall-chassidishe-litvak-sit-down-comedian-blogger-rosh-kollel-recovering-sportsaholic-with-no-concept-of-time-and-little-patience-for-most-things] is not what you will look for in a wife.
Love is individual. Find out what makes your mother-father-brother-sister-wife-husband-child-bubby-zeide feel loved and act accordingly. If you say it and don't show it, then, as the line goes in Rabbinic literature העיקר חסר מן הספר - The most central element is missing.
