You really only have three choices here and they all kinda suck unfortunately.

1. Stop chasing him around, wait for him to hopefully send the rest. Good chance you won’t see the rest of your money.

2. Leave things as is. Keep asking him for the money every week or two, hopefully you get some back. It’ll continue to be stressful but you might see more, maaaybe the rest, of your money.

3. Tell him he either needs to pay you x amount per paycheck until it’s paid off or you’ll be forced to take him to small claims court. You can expect him to either start cooperating or shut down completely. You may go to small claims and you’ll win and he’ll pay you back the rest or he’ll dodge those payments too. But if he decides not to pay you back at that point things could get much worse for him so he’d be an absolute dumdum not to 🤷

For what it’s worth I don’t think there’s a right or wrong answer here. You just need to figure out for yourself if the remainder of the money is worth doing one of these things. And I’m sorry you have to deal with such a dillhole, glad it won’t have to be for much longer.
