Love is wanting to be with someone all the time.It is accepting the other person with all good qualities and bad and not wanting to change any of them. It is wanting to give affection and approval and comfort and everything that is oneself,demanding nothing in return. It is - love is very difficult, Julia. It is an ideal, rarely achieved in reality because we are all selfish and imperfect beings. It is a dream, a goal, something to be aimed for.
