Cheater is accusing me

[p0nychick]

I recently found out that my husband had cheated on me with a woman I know. I honestly, accidentally found his emails about pictures she had sent him. he has confessed and told me that he had slept with her. I found an email she sent to me and replied to all ( other people were on that email) I stated that she was a whore and that she broke up my relationship. I sent her husband an email because I didn't believe she told him. I never have threatened her. She is paranoid and thinks I have the pictures and thinks I am going to send them to many people. I never said I would do that. She said she is going to sue me. What can she sue me for?
