And how in the world do you expect to raise a child if the ONLY reason you feel is necessary to talk to your W about is medical issues?
What about education, activities and all the other stuff in a child's life that needs the attention of BOTH parents?
Here is the bottom line... you can continue to say "I can't even look at my W as she makes me feel disgusted and angry" (chances are she is thinking the same thing about you) or you can tackle those feelings on your own and present something different to your W. What you are doing now, IMO, is participating in the equivalent of a grade school staring contest. This time though your future and the future of your child is at stake and the "game" becomes awfully dangerous.
Do yourself a favor and learn the basics. Don't just hope you heal, make a plan *to* heal. Remove the term "false hope" for your vocabulary. Find a way to deal with your anger/disgust and learn how to stop reacting on emotion. If you take those steps and really do the work your life will get better.
