How to manifest karma for someone who completely tore my heart apart?

I truly loved a man for 5 years. He turned out to be a major liar and it completely broke me. But he had it all when I last knew him: a successful company, friends, loving family.. I want it all taken away from him cause he doesn’t deserve it when he can go around destroying complete lives… is there a way to manifest karma because I’m always stuck between believing it really exists and believing it doesn’t exist😓 give me your advice please..
