I am in full on anger mode right now. I find myself sincerely wishing for her to be miserable.

Thats not healthy.

I wrote up a big long letter to her, and considered posting it here, but I don't see the point in sending it.

It was basically just me telling her that she is dead wrong about me having an affair, and then I go off about how disgusted I am with her and her actions and how I have no desire to see her again, much less remain married to her.

Probably not worth even saying, at this point.
