How to make my ex regret cheating on me?

Anonymous
We were together 4 years and one day he decides to cheat. I am so close with his family and he just wants me out of the picture so he ignores me and gossips about me to people. How can I show him that I'm better off without him and also how do I explain to him that I want to be friends with him and his family regardless.
