How to politely ask ex-boyfriend to pay back the money

First of all, we need to find out whether he doesn't want to pay back or forgets to pay back the money. I think whether he doesn't want to pay back or doesn't remember owing money, he should tell him directly.

Of course, you can also gently remind him, such as sending a talk about the fact that you are short of money, so that you can gently remind him to pay back the money.

If he still pretends not to remember, ask for it to his face. If you think so, you and I are not friends or relatives. You don't have to pay for anything you own. I can't live alone. Even though I had to come back to help the beggar, I did something good. It's better than leaving it with your predecessor. Anyway, you must come back. Otherwise, you will never come back.

This money is hard earned by you, or your parents' hard-earned money. I have to come back. Take it back, even if it is wasted, don't leave it to an ungrateful or irrelevant person.
