It is lonely behind these boundaries. Some people-particularly those whom psychiatrists call schizoid-because of unpleasant, traumatizing experiences in childhood, perceive the world outside of themselves as unredeemably dangerous, hostile, confusing and unnurturing. Such people feel their boundaries to be protecting and comforting and find a sense of safety in their loneliness. But most of us feel our loneliness to be painful and yearn to escape from behind the walls of our individual identities to a condition in which we can be more unified with the world outside of ourselves. The experience of falling in love allows us this escapetemporarily. The essence of the phenomenon of falling in love is a sudden collapse of a section of an individual's ego boundaries, permitting one to merge his or her identity with that of another person. The sudden release of oneself from oneself, the explosive pouring out of oneself into the beloved, and the dramatic surcease of loneliness accompanying this collapse of ego boundaries is experienced by most of us as ecstatic. We and our beloved are one! Loneliness is no more! In some respects (but certainly not in all) the act of falling in love is an act of regression. The experience of merging with the loved one has in it echoes from the time when we were merged with our mothers in infancy. Along with the merging we also reexperience the sense of omnipotence which we had to give up in our journey out of childhood. All things seem possible! United with our beloved we feel we can conquer all obstacles. We believe that the strength of our love will cause the forces of opposition to bow down in submission and melt away into the darkness. All problems will be overcome. The future will be all light. The unreality of these feelings when we have fallen in love is essentially the same as the unreality of the two-year-old who feels itself to be king of the family and the world with power unlimited. Just as reality intrudes upon the two-year-old's fantasy of omnipotence so does reality intrude upon the fantastic unity of the couple who have fallen in love. Sooner or later, in response to the problems of daily living, individual will reasserts itself. He wants to have sex; she doesn't. She wants to go to the movies; he doesn't. He wants to put money in the bank; she wants a dishwasher. She wants to talk about her job; he wants to talk about his. She doesn't like his friends; he doesn't like hers. So both of them, in the privacy of their hearts, begin to come to the sickening realization that they are not one with the beloved, that the beloved has and will continue to have his or her own desires, tastes, prejudices and timing different from the other's. One by one, gradually or suddenly, the ego boundaries snap back into place; gradually or suddenly, they fall out of love. Once again they are two separate individuals. At this point they begin either to dissolve the ties of their relationship or to initiate the work of real loving.
