I am having an affair with a married man who is my coworker. I did not begin the affair, he pursued me. His wife does not know. I feel guilty about it but I am in love with him. He says that he loves me but that he also loves his wife because although she is abusive and he feels no attraction to her she was there for him when he was very ill two years ago. Are my actions unethical? If she doesn't know and I am truly in love with him is it okay? Are his actions more unethical than mine?
