C S Lewis

Loneliness, I am pretty sure, is one of the ways by which we can grow spiritually. Until we are lonely we may easily think we have got further than we really have in Christian love; our (natural and innocent, but merely natural, not heavenly) pleasure in being loved—in being, as you say, an object of interest to someone—can be mistaken for progress in love itself, the outgoing active love which is concerned with giving, not receiving. It is this latter which is the beginning of sanctity.
