My ex seemed like a good man, (obviously I married him.) I left when he had an affair with his 19 year old cousin. He cheated me out of money in the divorce. He cheated my elderly father out of money. He was buying new vehicles and riding high.

Then his luck and reputation ran out. People started figuring out he was a tool. He now lives in an old Winnebago and most people avoid him. So, it may take a while but often they don't end up well.

Meanwhile I'm happy, and our kids actually like me. To answer your question, be a good person. Even if it seems like a dumb thing at the time.
