MY father passed away when i was 7 - and i dont really remember much about him prior to that. I dont think that he needs to be part of his life if he doesnt want to be - probably better to be completely out rather than half - hearted.

You seem so strong, its amazing to see such a great attitude! IF you keep that up your son will definaltely see it in years to come and will respect you so much for it. Always tell him the truth about what has happened!
