Congratulations on getting to "the other side." Your post is a great encouragement to everyone here who is just facing the prospect of divorce. I'm glad to hear you are taking things as they come, not rushing anything, and enjoying your new singleness.
Kudos to your daughter who has expressed support for you, too. We don't always see things objectively when we're in the middle of them. I hope your kids will see how you've handled this crisis and try to do better themselves. It's possible!
I also had to smile at your description of your Ex's response to the news you are dating. How typical! How predictable! How hilarious! Image your Ex being jealous of your ability to move on and - gasp! - have another man find you attractive! I'm glad you've found companionship with someone you all ready knew as a friend. I was divorced 14 years ago and when I remarried, I married a dear friend. It was a good decision for us. You are wise to make good choices for yourself.
Be blessed and keep smiling. The future is never the way we think it will be; we just have to learn to roll with the punches.
