My mother was so locked in her angry relationship with my Dad that she could not see the effect that this had upon her children and her wider relationships. She had a huge chip on the shoulder about being a woman and being seen as inferior - highly intelligent woman with parents who devalued women's education. It was sad that she let this understandable bitterness rule her life and relationships rather than rising above it in some positive way.
She was an angry lady inside and this spilled over into an inability to show affection - did she ever tell us she loved us or give us a cuddle? - no. She was herself too damaged.
She died a fair while ago and it took me till then to begin to understand the roots of her personality and behaviour. But the dawning of this understanding was helpful to me to be at peace.
I am not trying to diminish then pain that posters here have suffered, but just wanted to say that hanging on to this hurt is in itself damaging. It will not matter to your mother and do her no harm - but it might do you harm. I did not work this out till she died and hope that others will be able to gain that understanding before then, as absence of forgiveness can be very damaging to the individual.
The other thing that set me thinking is the fact that I too am a mother - like so many on here of course - and the positive result of my difficult mothering was that I made a special effort to be a good mother myself. I did not always succeed, and, not unsurprisingly, some of the failings mirrored my mother in ways that I regret.
But I have excellent relationships with my adult children now, so I must have got something right - or maybe they are just more forgiving by nature.
It is fine to vent the anger felt towards imperfect mothers; but to hold this in your heart and let it damage other relationships (especially with offspring) is stabbing oneself in the back.
I will be 70 next month and the pain is still with me - I would like to feel that these words from a relative oldie might help others to make an attempt (however hard) to let go fo some of this hurt and allow yourselves to live at peace. The key for me was asking myself why my mother behaved as she did.
Good luck to all who are struggling with this problem.
