Ah OP. My mother had to get married, never wanted a child, I ruined her life, she couldn't go through with the back street abortion and when abortion was legalised was extremely enthusiastic. When I was about 22/23 because we had a close relationship told all about when she sat in the abortionists. By the time I was 21 she was on marriage three. My friends all thought she was marvellous - so much fun. She was such a party girl, so glamorous, so popular, so marvellous, the best at school essays, the most talented dancer, etc, etc. I was so in awe.
I was never hungry, never hit (except occasionally and the one occasion she lost it and laid into me), I had the best of everything, not a deprived childhood in any shape or form.
But, I was plain and boring and dim and a klutz. I wasn't allowed to wear or have pink (not even my NHS glasses) because pink was for pretty girls. Y feet were wrong, my hair was wrong, my teeth were wrong, my personality was wrong.
I never understood how awful it was until my days old baby was in my arms and the love was so strong it hurt. I knew I could never do anything to hurt his feelings and that my being existed to love, nurture Nd encourage him. I cried for days because I knew I that moment I had never been loved. I didn't stop loving her (I might have now and it hurts) but I stopped liking her and a little bit of my childhood died.
I know now she is a narcissis. I know now she frustrated and made a lot of people unhappy but I was for most of my first two to three decades regards as the "odd" one. Two husbands gave up on her, so many arguments with friends and neighbours. Some of her friends with whom she no longer has a relationship still send me Xmas and birthday cards, sometimes with kind words. 40 years ago they laughed and said I was a funny girl. I think they know which one is "odd" now.
I am 56 and still wish I had ever pleased her and it saddens me. I look at my DC and hope we have something more precious that will endure.
I am sorry op, it is hard. I wish things were different but I understood a long time ago that only the future can ne changed. The past is often to be mourned but always to be learned from.
