My brother blames me for his divorce?

He told me his wife would scream out my name during sex and she would always ask him why he can't be more like me. He said she told him he was in love with me and she knows that i feel the same way about her. He asked me if i ever had any kind of affair with her and i said no but she did try to give me oral sex but i stopped her because she was my brother's wife. I have no feelings towards her whatsoever. He told me I'm a selfish bastard who loves to ruin his life and steal his wife. Bottom line i had nothing to do with his EX wife's obsession with me. What should i do?
