I think you've done some major healing to get to this point. I'm so proud of you. I've done a lot of healing myself, except when it comes to my parents. If I saw a JW or even an old JW friend on the street, I can't say that I'd have any hard feelings toward them. Seeing my parents? That's a different story. So much water under the bridge there.
I agree that living well is the best revenge. Except I have no question that when my parents see me living well, their thought is, "Satan will give her whatever she wants just to keep her out of the fold. Of course she's happy." They really don't have a clue.
