Wow, I have no idea where you are getting your information, such as postcards send to Betty from the ex. I was intimately involved in this case as I worked for a forensic psychiatrist at the time. People fall out of love and move on. In fact, Betty's behavior is indicative of why Dan fell our of love with her. She became obessed with money, power, and prestige....not love. Had she loved her husband more than her lifestyle, they might both still be alive today. Also, even if a person falls out of love with their spouse, what right does that spouse have to kill you and your new partner? Why would someone try to control and demand that another's behavior align with their own? It's impossible to do. Betty Broderick was a mean-spirited, bitter spiteful woman who murdered two human beings. Just because a man trades his wife in for a "younger model" does not constitute abuse.
