My sister and I got along until she blamed me for my daughter's behavior instead of helping me. She could have helped with my daughter instead of enabling her to disobey me. Then, she rejected my daughter and made it worse.
We get along now but we are not very close. I always felt she judged me. And still does.
My mother was a part of it, too. But I'm not sure if she played us against each other. I never picked up on it if she did. My mother always told me I was her favorite because I was the most like her. She probably told my sister that too.
I wish we could all just start from today and live our lives without all these past hurts eating away at us.
I'm glad to hear you became close with your sister. You can't blame yourself for what you didn't know as a child.
