If you are not capable of being alone, your relationship is false. It is just a trick to avoid your loneliness, nothing else.
Real love is not an escape from loneliness, real love is an overflowing aloneness. One is so happy in being alone that one wud like to share.
Become aware of your aloneness - which is a reality. And it is so beautiful to experience it, to feel it, because it is your freedom from the crowd, from the other. It is your freedom from the fear of being lonely.
