I am very sorry for your pain. I understand how you feel, and I agree that we all are better people for what has happened to us. I know that this happening to me has taught me a lot. You said you were going to move over to the divorced section; does that mean you are filing? If so, I am very sorry to hear this. Just wanted to reach out and say hello. I don't know what advice I can give, except do what is best for you and remember that this isn't about you.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
