First, you should collect evidence that he stole money. After collecting the evidence, you should find a time to talk to your boyfriend about it and see if your boyfriend admits to stealing money. If he admits the fact of stealing money, then you can choose to forgive him, but you need him to write a guarantee that he will never steal your money again.

And after writing the guarantee, you need to give him a deadline to return the money to you. It is impossible to just admit your mistake and write a guarantee without paying back the money. If he doesn't pay you back within the specified time, you need to urge him to pay back the money again, because you two brothers still have a clear account, not to mention that you are not married.

If he keeps dragging his feet and doesn't pay you back, you need to use the evidence you collected before to threaten him to call the police and arrest him if he doesn't pay back, so that the police can handle this matter well, because after all, if you handle it privately, he may not care too much because you like him and don't pay you back.

But once this matter is brought to court, it will definitely play a deterrent role to him, because the law is merciless and everyone is equal before the law, so your money will definitely come back soon. After you get the money, you need to break up with him because he has a personality problem.

You have given him a chance, but he didn't cherish it, so you must not be soft-hearted at this time and must break up with him. Such a man is the life of eating soft rice, maybe he will get married in the future, and you will earn money to support your family. Would you rather earn money to support your family alone or work together?

Don't be sad, because such a man is not worth your sadness. He is really a love rat. You should make your life better and better, instead of being entangled with such a man.
