A of A and no money to defend?

Just recently a coworkers estranged wife has decided to file an A/A complaint against me. He is separated from his wife and we know each other on a social level as well as a peer level… His extranged wife saw us out to lunch (we are lunch buddies at work as well as other people from our dept) a couple months after they separated and jumps to the conclusion I am his mistress or something! I have no money to defend my self against this crazy woman’s claims. I barley make ends meat and live paycheck to paycheck. What are my options?
