I agree with the posters above, you don't need this in your life. I realize that she has always treated you like this and it won't be easy. A child has every right to be loved and treated with respect and when you are not you feel confused and even have a sense of guilt. Sometimes feeling that it was something that you did. Well, you are not responsible for this, you have done nothing to deserve this treatment, then or now.
My childhood was a little different but just as painful. Dad left when I was five and my mother remarried when I was seven. I suddenly had a step father that did his best to copy all the horror stories that you may have heard about stepfathers. He hated me and told me so and showed me every opportunity he had but of course only when no one else was around. I was, like you confused and felt very much alone. I always felt like I was paying a "price" for something that I never remembered doing. And I wanted to "keep the peace" something that in retrospect was wrong. I was fortunate however in that I had a loving and nurturing mother, she got me through those many years.
I told you this story with pain in my heart for you. But I can tell you Dazzling that your life now does not require that you continue this relationship. Stop looking to her for approval, it is not necessary anymore, you tried and she failed, not you.
Stop looking to her for any emotional satisfaction I don't believe that she is capable of giving it, quite honestly she may be jealous of you....have you ever considered this? What has happened to you is not your fault (period) You did nothing wrong, it is her problem, move forward dear, now.
No one can make you happy, no one! You are responsible for your own happiness. People in your life that do love you can make you "happier" but you must have the ability to make yourself a happy person. Doesn't it make sense that in this short lifetime that we are given that we would want as many positive/happy people in our "inner circle?" People that ADD to our lives not subtract...
You know, someone once told me that if I indeed have enough good friends to count on one hand---then I am very fortunate. Friends that would give you the shirt off their back when you were cold. Now that is something, something that we should all strive for and be grateful for. How do you do this? Well a way to start is to to like yourself, be happy with your life and open yourself up to being a good friend first to others. Close the emotional door on this matter and get on with your life, it is waiting for you.
You have to realize that YOU are a valuable asset to yourself and others and you do not have to wallow in this damaged relationship. Be positive, be happy, be a value to yourself and others and your life will benefit in so many ways.
I am sorry that I rambled on so, but I relate closely to your situation. And I got past the pain and realized long ago that you choose your own path. I chose not to let it make my life miserable.
Good luck to you, find those who love you and nourish that love and friendship.
