Lies

So basically I have been divorced for a month or so. I have been separated for almost 1.5 years. Well, a few days ago, my ex got arrested for sleeping with his bosses daughter who is 16. She was 15 at the time they had sex. So he's probably going to prison. Then his girlfriend contacted me and proceeded to inform me that they have been seeing each other for almost 3 years. Now, I believe this because it lines up. I found pictures she had sent him at the time, and my son has mentioned her since then, so I knew something was up. I didn't realize that. Well, since then, we've been talking, and I've found out way more than I would ever like to know. 4 girls from work, a mom from daycare, random people on craigslist, God only knows how many more that there's not a paper trail for. Basically, I have discovered that there wasn't a moment in our marriage where he wasn't cheating on me. The worst part is he never even seemed to feel remotely guilty. You know those signs a man is cheating? He didn't have the majority of them. I think he seriously just lacks a conscience. I think my best friend was more right than she will ever know when she diagnosed him as a psychopath. He literally has no regard for anyone besides himself, and the worst part is he can make you think he does. It's all such fucking bullshit. I really do hope he gets locked up for a few years because he deserves it. His son doesn't need that man as an example of what a man is. He is not a man, he is a selfish, dick-driven child. I honestly think he is a sex addict, although he will never admit to it to get help. He is going to be like this for the rest of his life, and I might as well just accept it. I can't do what I really want and kill him.
