As a WAH once, I never looked back. I did not have children that tied me to her though. If I did... I wouldn't have left. I'd be dead from a heart attack. But lets say I did leave, I would have made it very clear that there was no future, I would not give her hope that there would be.
That was over 9 years ago. I wonder and hope tht she is happy, but that is about it. Once, I did send her an email at the height of my depression in LBS land, I figured that she could derive a certain ammount of satisfaction from what I was going through but I made it clear that I had no regrets.
But this is just me. I can only speak for me. That is what I did as a WAH.
