Let her do the work of divorce. She wants it, she can have it, but not with your help or approval. If she's hell bent on it, let her do the heavy lifting. Sit back relax watch the "fun" and take the stress off yourself. There is nothing you HAVE to do here. Let go and let God Tad.
Focus on the control of you.
As for her hurtful words they're just words. (Believe none of what they say, half of what they do...remember?) They hurt because they were a direct slap meant to take aim at your self-worth and value. She wanted to hurt you, if she didn't care she wouldn't have wanted to hurt you either.
You have value Tad, you matter and you know you have much to contribute to the world and others and she can't take that. There are others that DO love you, care for you, support you and want the best for you.
