If You Loved Me... "d" or no "d"?

What is a letter worth? I've recently asked myself this poignant and absurd question of how one single letter could so drastically alter the meaning of an entire phrase or in this case the meaning of an art piece. This quick to bloom piece came guided by a clear vision and under known circumstances yet once I asked myself whether the title should be "If You Love Me" or "If You Loved Me", I realized how different both meanings were and how both would send the viewer on such different paths. In the end, I did decide to go with the subjunctive tense which seemed filled both with rosy promises and happy dreams and tainted with sadness and bitter regrets. The allure of the ambiguity won me over.
