When a person falls in love what he or she certainly feels is 'I love him' or 'I love her.' But two problems are immediately apparent. The first is that the experience of falling in love is specifically a sex-linked erotic experience. We do not fall in love with our children even though we may love them very deeply. We do not fall in love with our friends of the same sex - unless we are homosexually oriented - even though we may care for them greatly. We fall in love only when we are consciously or unconsciously sexually motivated. The second problem is that the experience of falling in love is invariably temporary. No matter whom we fall in love with, we sooner or later fall out of love if the relationship continues long enough. This is not to say that we invariably cease loving the person with whom we fell in love. But it is to say that the feeling of ecstatic lovingness that characterizes the experience of falling in love always passes.
