Reading your blog I first want to say how proud of you I am for writing it. I know it's hard to share and put your feelings out there.
When it comes to our parents those feelings are very deep. I know that I have had my share of ups and downs with both my parents.
I realized at some point just like you that if I wanted to have a better relationship with my mother that I had to treat her the way I wanted to be treated. It was amazing to me how our relationship changed for the better when I showed her the love and respect and admiration that I wished she would give me. With no expectation from her I did get that back, but first I had to give it to her.
The connection to the parent is profound. When we can look a little deeper into why we choose our parents and see the big picture it becomes so much easier to see them as they really are; human beings just doing the very best they can at this moment from the place of awareness they are at.
