(Click Q&A for Siddhartha.)
Real love is not between two but what two are IN. It is not dependent on time or space or whether one stays together or leaves, it is not dependent on anything in this world to be and so "love" of a human is not real. It is limited by beliefs and making sure that one does what the other wants or they withhold the love. True Love cannot be withheld, it does not change or move or alter.
