my ex was into scams 419 and i knew it even though i never told him i knew. See I am a christian i just prayed that God would change his heart . As time went on he broke my heart and dumped me it happens no big deal , but that not the case i am married now and happy but i know some information about him my (EX) that could keep him out of jail as his playing with fire and if he doesn't slow done he my EX will get caught and go to jail for a long time. Should i tell him that the police are on to him. Risking major issues/ or lying to my husband my everything, or should i just leave him to the hands of God as it not my place any more and he know what risks a involved. Is just that he is just 28 years old and has a young daughter.

pls help advice,
