That is as insightful and introspective of a post (or any other correspondence) as I have EVER seen from you, and you've communicated a lot since I've known you.
I'm exhausted at the moment, and can hardly keep my eyes open, but I will say that -- based on what you have shared about yourself and your marriage -- I don't think I can disagree with ANY of what you've written here. I think it "rings true," and it's a good thing that you're able to identify your role in your past relationship dysfunction.
