Unfortunately, history and "Mad Men" have proven otherwise. So, when a disappointed bride decided to consult the moral compass of the internet otherwise known as Reddit's "Am I the As*hole" about whether or not she would be wrong to ban her parents from her wedding because of their spicy history, people were quick to help deem a verdict.
My wedding is coming up soon and my parents were telling me about how they met. They started telling me how "romantic" their story was. Long story short, my dad was married to someone else and they were trying to get pregnant but they couldn't.
He started having an affair with my mom, who worked with him and knew about his wife and them trying to get pregnant, and my mom got pregnant with me. When this happened, my dad left his ex wife and married my mom.
