This guy I was seeing, we'll call him A, is now accusing me of defamation of character. He and I ended our sexual relationship approximately 3 months ago. He was someone who had a girlfriend, and slept with multiple women on the side without his girlfriend knowing (I was one of these women). He and I were very close friends and I knew of his pattern with women.
Before I started my relationship with him, I was involved with another man (call him B) and after being raped by B, I engaged in activity I probably shouldn't have but did (i.e.: getting him fired from his job). Prior to A and I consummating our sexual relationship, he found out about the things I did to B. He still had no problem getting involved with me. After we were sexually involved, I spoke with A and confessed to all of the bad things I did to B, because I thought A was my friend and he would understand why I did all of these things. I told him about everything I did but we didn't talk about the rape, it was mostly just detailing the things that I did. I told him that doing those things to B made me feel better and I'm glad I did it because B deserved it (at the very least) in my opinion.
Later on, A admitted that because he was scared that I might do the same thing to him as I did to B (i.e.: get him fired from his job), he decided to voice record all the conversations we had, without my knowledge. We stopped seeing each other after a few weeks of that and it was mutual.
Recently I found out that someone sent his job a letter describing sexual assaults perpetrated by A. As a result he was fired from his $150k job. He told a friend who told me that he is suing me because he thinks I did this and he has evidence because of the voice recordings. I have no idea what kind of damages he is going for and I am very poor. I can't afford a lawyer and what's worse is that I haven't committed any of the acts he's accused me of, I haven't spoken to him in months.
I should mention that we are in NY so the law of one-party consent applies to him recording me. Does it seem like he has a substantial case against me? Is it possible that these voice recordings will substantiate his claims that I somehow got him fired?
