HPD Male as a parent

how children react to both you and your partner's parenting also depends on where they are in their lifecycle.
In their twenties they are optimistic and usually supportive of their parents.
But it is pretty normal for children to distant themselves from their parents around the age of 30 and have lots of critic about their influence on the childhood. In your family there could surface some harsh words for both you and their father. (it could be something unexpected, in my family it was the high ambitions and expectations from my father I had incorporated in my life and career which made me angry at my parents.)
After a few years they will understand how it was and how you both tried to cope with his disorder and parenting.

To answer you last question, about compensating. You did the best you could (congrats to you for recognizing you partners issues and its influence on your children!) and there is nothing to be done about it now. Children grow into adults no matter what and in the coming years you can start to interact with them as adults. One of the aspects of their life will be having a HPD father and a mother who tried to compensate for that. You will be able to talk about it with them and they will answer your question. But I hope you know that you should not feel inadequate, however they answer you.
One can regret how things were and one can express sorrow for the grieve a child has experienced (this is very healing for the child, to get its grieve acknowledged) but when your intentions were of a good nature than you are not quilty or inadequate. You are not.

Sorry if I am too heavyhearted in this post. I mean very well
