I'm going to tell my daughter her husband should get a job to pay me back an $1,800 loan I gave them
That's a lot of money. Why did you loan them $1,800?
They suddenly needed a car and borrowed the money from me.
Fair enough to expect them to pay you back the money they owe. They did borrow money from you.
I'm going to be telling my daughter that all he's doing at home is talking to his fucking stupid girlfriend's, listening to stupid music and even playing computer games. He earns my respect and I really want him to do something on his lazy ass.
Although I could have worded it a little bit more friendly, you have every right to be angry at her husband if you see that he is not doing his job and not paying you money that they have owed you. I do hope you help him find a job so that you can get repaid sooner than later.
