Hiya Carter,
It doesn't just go away overnight. How could you
have spent so much time with each other and done so much together without
creating all those memories? Can you just wipe it out? I couldn't. I'm 3
years on from the split and have only in the last 6 months begun to feel
dispassionate about my ex-wife. I still worry for her well being (and
sanity!

), but don't miss her or want to go back.
Its a very fine line between love and hate.
But you will heal.
I never thought I would. But when you least expect it, you do.
Keep on looking after the 'bairn' and being a good dad.
This
whole game is one step forwards and three back.
Best of luck
Mike
