I think you've been given a surprising lack of support / understanding on this thread Host.
"Accept what happened and move on with your own life." Yeah, it's that easy!
I, too, felt that I lost my mother when my father died. My mother turned into a demanding, selfish, critical, unsympathetic shrew when my father died, and got worse and worse until her own death a few years later
. On one memorable occasion she screamed at me that it wasn't fair that my husband was alive when hers was dead....
My husband was 34 years old at the time.
She used to turn up unannounced at our house at all hours of the day and night; refused to go to counselling; rang me or visited me every single day to talk about my dad and never once asked me how I was doing (I'd lost my dad, was caring for my young baby AND my childlike mother, and had gone back to work after maternity leave a month before dad died - this was back when maternity leave was only 6 months - so life was tough for me too, not as tough as for her, but still tough).
It was as though all her motherly feelings had been wiped out with my dad's death.
I'm an only child. I did everything I could to support my mother after my father died, as did my DH, while friends and cousins / aunts etc drifted away once the funeral was over. Yet nothing I did was enough. Mum wanted me to replace my dad, and do everything that he had done. She would ring me at 3am to tell me that she needed me to go round and fix something in her house. Or, if I was at work, she would turn up at reception and ask to see me. It was horrendous. She lost all sense of perspective. She was unwilling or unable to show me any motherly love. I needed time and space to grieve for my father, yet my mother needed the opposite, and demanded all my time and emotional energy. She stifled me. A year after he died, I had a breakdown. Mum's response: "when are you going to get better, I need you to do Xxx for me."
Btw she was only 63 years old, and in very good health, when she was widowed.
I remember having a conversation with her about an acquaintance whose child had sadly died.
Me: "there's nothing worse than losing a child...."
Mum: "no, losing your father was worse."
I still can't forgive her for that, TBH.
I can't forgive her for choosing to stop being my mum.
If my DH dies before me, I will do everything in my power to reassure my children that I understand that they are grieving, and that I love them.
Being widowed does NOT justify ceasing to be a parent to your children. Of course the grief is different; when you lose your partner, your whole life changes and there is a gigantic, lonely, scary void where they used to be. But you are a parent for life. Your children are still there.
So - OP, I understand.
