The purpose of Love is to experience itself in its physical manifestation — Life.

Life's purpose, or the answer to the question: "What is the real purpose of life?" and the related questions as "What is the meaning or purpose of existence", "Why do we exist"? or even "What is the origin of life" can be answered in one word that is not a word per se but a feeling; this feeling that is LOVE. The "meaning of life" question is thus an abstraction for we must first understand what life really is. Life is Love. It is Love that expresses itself as Life; not the other way around.  In other words, the purpose of Love is to experience itself in its physical manifestation — Life.  Life is Love in reality and yes, this can and should be taken quite literally so.
