Treese, I am so sorry you are still having to face all this.
Maybe "knowing" will possibly ease some of the uncertainty.
Maybe H didn't react in quite the way you would have expected because in his heart he already knew the results, who knows.
Nothing that can be done now as the child is here and has been for what 8 years. It's hard I know but try to focus on your children, particularly your d, I hope she gets well soon btw.
There is absolutely nothing you can do about your h at the moment,so put your energies into things you have control over.
I hope you get a friend over you really need some help and support in RL right now.
Hugs to you,take care.
