HELP! What should I do???

So I did a thing I did not want to do. A friend of mine called me in tears two weeks ago. She, her husband, and their two yr old daughter were being kicked out of her father's place and had nowhere to go. After a long talk with my husband, we decided to help them out. Her husband had been let go from his job due to COVID-19 and her hours at work were greatly reduced to just two days a week. They aren't anywhere near our level of financial stability. But I had people help me out when I wasn't stable, so I felt I couldn't say no.

So it's been almost two weeks since they moved in, and it's pretty bad to be honest. From leaving dirty diapers in the kitchen trashcan, eating up most of the food we had that was supposed to last us all month, needing rides to places because they didn't even have a car, to her husband literally keeping me up and waking up my baby late at night from his damn gaming sessions. Her husband hasn't been trying to find another job, he doesn't take care of their daughter, and all he does is play video games, eat, and sleep all day. Then when their stimulus check arrived, the first thing they wanted to buy was a fucking Nitendo Switch. They'd paid no rent, nothing for groceries, and nothing for gas or utilities. So when I asked why didn't they just buy a car or things they actually needed, they were shocked. Like it never even crossed their minds to actually buy something other than gaming shit. After I mentioned the car, they looked around online and bought one that same day. It's a little junker, but will be a great A to B vehicle for them. But after they got the car, they started talking about the Switch again. So when we got back to my house, I said we needed to talk rent and such. They agreed to $200 a month until their out, and half on groceries. But they still went and tried to buy one online after we talked. I'm just appalled because their daughter needs clothes, a carseat, shoes, etc. And they want to wait until they get their tax refund before moving out.

But I don't think I can hold out that long. I'm getting more frustrated every day and idk what to do. It's not my job or place to tell them what to spend their own money on, but they're literally making the dumbest financial decisions and I'm cringing so damn hard and feel like I'm just being taken advantage of in the process.
