There really isn't a difference a true friend (friendship) would do the same things as someone who claims to love you would do. Of course intimacy doesn't always get involved in a friendship, but being able to count on your friend, confide in your friend and be respected by your friend is appreciated and guaranteed. Loving someone also comes with all of the above and more. A Good relationship has a Great friendship attached to it whether or not sex is involved. So to answer your question I don't think there is a difference.
