Mountain, I have been in the place where you are. It took a long time for me to realize that friendships change through nobody's fault. I finally understood that if the friendship was draining me, then it wasn't worth keeping up. I can't begin to count the number of friendships over the years that have faded away. When I look back on those, there was always a new person coming into my life to replace those who dropped out. I think that friendships are to serve a purpose, and when that purpose is served, there is no need for that particular friendship. People are in our lives for a reason, and we don't always know what that reason is. I am blessed in that I have good friends, but who knows how long they will be in my life? I enjoy them while they're here.
