Hi Rickman!
It must be so hard doing what you are doing and wanting the best for your children in the face of an arsey ex!
The others are right you have come so far - you've made a new and happier life for your family - which will reap rewards far higher than it feels right now, I'm sure!!
The anniversary of parting must be a milestone and all milestones in life lead to a bit of reflection and navel gazing. But do try to be balanced about it and give yourself the credit you deserve
