I found out my ex's former affair partner was in a fatal car accident, and im thrilled

A few years ago, my ex had an affair with a co-worker. She lied to my face about it, and after he left me for her, she threatened me AND my children, got me jumped, and made fun of how heartbroken I was. She said the most cruel things to me for absolutely no reason. This woman would purposely sleep with taken men, and called herself a "prpfessional homewrecker". I wasn't the only one she did stuff like this to. About a year after her and my ex stopped seeing each other, I found out she was in a fatal car accident from drinking and driving. The smile that spread across my face was unreal. I felt SUCH a wave of happiness and satisfaction. Now before anyone jumps down my throat, I KNOW she didn't owe me what my partner did, and HE could have said no, but its just the fact she was a HORRIBLE person in general. I have never been happy about the death of someone before, but this was so satisfying. Call me an evil person if you want, but I strongly believe in karma.
