I AM BEING CALLED CALLED CRAZY. YOU TELL ME WHO IS CRAZY ?

My ex remarried his ex after 7 years of being divorced. He bragged that he gave her a nervous breakdown. she actually ws put in an institution. He remarried her so he would not have to pay his900.00 child support, plus get his tax breaks. she made him get a vasectomy and and repay her 15,000.00 she spent because he divorced her for another woman and went on a huge shopping spree. They remarried STUPID ME, almost had an affair with him, but I did not. I came to my senses. Crap hit the fan. She knew something was going on, so he brings my name into it. Why I do not know.She called 100's of times I would not answer the phone. trying to created down a bit.(I didn't know he was putting everything on my shoulders) My husband finds his xrated e-mails and crap hits the fan. I came clean with him. I told her about the e-mails. She said you know my address send em to me. She is telling everyone that I am REALLY CRAZY they don't know me. . I know I was wrong but I did come clean. to I have done nothing but told the truth. AMI THE CRAZY ONE? How should I handle her mouth. He is causing me problems in my business which I could return the favor. I could send the e-mails. What should I do. I am feel stupid for ever talking to him. I am so glad nothing came of it (UALLY) I am the one as usual when it comes to him being "the craz one" he tells her just enough of the truth to make it believable.
