You are just going through the post D process. I did this exact same mulling over the "did I really do the right thing" with endless permutations, still do occasionally. The problem is you made the decision, so you are shouldering the guilt. I think you did the best thing for your kids, stayed until they were older and then took back control of your life. Which is what it's all about. I felt like I was suppressing my identity in my prior marriage, I couldn't go on so I left. I don't hink I could have stayed true to my self, kind of hard to explain and I wonder if anyone understands this. It would have sounded a lot better if I said my ex was a crack ho or something.
