The only thing I'd like to add is my admiration that you isolated your daughter from the threat even though it cut you off from your Mom.
You are a true Father that puts his child above all else.

One other thing is about your feeling of hate.
Don't expect to feel too much of a change if you ever do let it go.
I mentioned in another thread about my 25 year hate and disgust toward my father for just up and walking away from a wife, me and 4 other children.
Last year I called him up out of the blue and we talked.
There was no feeling of "release" or letting go of a life long hate.
I just don't get as pissed off like I used to or think about it nearly as much.
But I am glad I "let it go".
Hopefully you'll do better.

Take care.
