Friendship is the foundation of real love. It is totally normal and healthy to develop that sort of relationship with a friend. Some people are scared of losing a friendship if the relationship ends, but I think that depends on who you are as a person. Are you selfish and if things end will you be mean, jealous, or clingy? Or are you a true friend and if things end will you continue to share yourself with that person as a friend?
