javotte,
Your Mother sounds extremely jealous of you; I don't think she could actually "cope" at all with having a daughter as she probably thought you were competing with her for male attention. Hence her actions towards you which continue to this day.
The fact too that you felt happier at Uni when you were away from them speaks volumes.
You cannot even express your very real anger and pain openly; they have taught you that your feelings and by turn you don't matter.
Their actions towards you as a child and now adult would have been enough to give anyone very real and complex emotional problems to deal with. I am not at all surprised you ended up with an eating disorder because they caused that to happen with their continuous comments about your appearance.
Theirs were and are not the actions of loving parents, these are all the actions of emotionally damaged and toxic people.
Their toxic behaviour is now being directed towards you in the way you are bringing your children up. Such problems you see can easily become generational in nature; don't let your children be affected by them as you clearly have. Build clear and firm boundaries between you and them.
What does your H think about them?.
It is okay to limit contact, infact I don't think I would want them in my life in any shape or form but that is easy to write and hard to do.
What you want from them - an apology for how they behave?. I tell you now, you won't get that or anything even close to it.
This is your Mother's issue and not yours to carry. It is NOT your fault she is like this and she could well have an untreated personality disorder. They both could. That is NOT an excuse for their behaviour in any way shape or form, their actions are abusive. You did not make her this way and your parents both failed you utterly.
I still think for what it is worth you are in denial/disbelief of your situation and what actually happened to you. It may well dawn on you more over time and more memories will surface; you have started a very long and painful process of recovery.
I would urge you too to seek professional help. BACP have a list of counsellors and they won't charge the earth.
