Katie,
I am so sorry you had to go through this.
Although you feel he got off easily, you need not worry about him anymore. Tell him to eff off and leave you alone. Whether he got left off the hook is not up to you, it’s up to him and his karma. I would move forward with life. It’s not always going to be fair, especially for us women, but just know that the only thing you have control over is yourself and how you allow others to treat you. Pay him no mind, for he has shown he is obviously not deserving of it. Keep your head up. You’ve been so strong and you’ve gone through so much. Be kind and gentle with yourself, by focusing on your own needs and not worried about others is such a great investment you can make on yourself. Also, if he is still cheating on his gf, he’ll eventually get caught… just be glad you aren’t his gf.
Though I run this site, it is not mine. It's ours. It's not about me. It's about us. Your stories and your wisdom are just as meaningful as mine.
