Three years ago my then wife confessed to an affair with an old high school boyfriend. We tried for 18 months to reconcile but she ultimately decided to leave. We've been divorced for a year now. We aren't really on speaking terms but occasionally she'll post a cryptic message on social media taking a shot at her past life and the people in it, including me, and makes herself look like the victim. I never respond but it does hurt both me and the friends she left behind. Any advice on how to deal with hurtful comments and lies after a divorce?
