A friend, or not?

I have had a friend for over 15 years of my life. I met her not long after I moved to the great state of Florida. I have always thought highly of her and her family. The longer we were friends the more they became like family. She has two wonderful children that I have watch grow into young adults. She has always been there for me, in all the bad times that I had gone through as well as those few good times and vise versa. Needless to say, in the past 15 years I to have grown into an adult and have made something of myself and I am no longer in dire need of her help and assistant. I still need her friendship though. I moved from Central Florida (which is were my friend lives) six years ago. At that time in my life I had experienced one of the most tragic things anyone could experience. I left and moved to North Florida to make a new and fresh start in my life. I did that and now six years later I feel as if my friend is not my friend. I also wonder if she ever really was? I can't share any aspect of my life with her anymore. She doesn't want to hear anything about my life, good or bad. When I try to speak to her about things that are happening in my life she honestly doesn't want to hear it, she will change the subject to something that concerns her. In the past six years she has been to see me maybe four or five times. I have been to see her more times than I can count. I have been feeling like our friendship is one sided and I'm doing all the work. I don't understand why this is happening? I will be honest, this has been going on now for a few years. It started not long after I moved. I wonder if the problem is that I have moved on and made a few of my dreams come true and she is still where she was when I left? I don't know. I have tried everything to keep our friendship alive. If it weren't for me we probably wouldn't even be speaking today. I wonder why I am the only one in our friendship who tries to keep it alive? Can someone honestly be your friend and not want or need to be a part of your life? What would be the point of a friendship then? I often ask myself why I care so much? Why do I keep trying so hard to make our friendship work? I can't do it anymore. I'm tired of not being able to share my life with her. Isn't that what friends are for? To share in our lives and to be there for us no matter what? What kind of a friend doesn't want to share in your life? A true friend would never do this, right? I would never do this to my friends. This is where my question comes in, is she really my friend or not?

It kills me that this is happening. I love my friend dearly as well as her family. There were times in my life if it weren't for her I don't know what I would have done. I have agonized over this for years and I'm so tired of the worrying over it. Should I walk away, or keep trying?

I know that my best friend has heard my complaining about this for a few years now, but you see she's a true friend. She wants to hear what I have to say no matter what. She wants to be a part of my life and I want to thank her for being my TRUE FRIEND! She is so good at listening to me ramble on and on. lol
