It is only when you let your heart out, and let it be known to the person you love that you love her, and consider her more than a "friend" that your heart can be really satisfied, even if nothing comes out of it. Friendship is a different feeling, a beautiful feeling, nonetheless, but love is love, and love cannot be friendship. When you are in love, you want that person, entirely, body and soul, and emotions and feelings, and heart and mind.

Yes, you can be "friends" with that person you love, but somewhere, in hearts of hearts, you keep expecting until you, or that person gets married or committed.
