So he is not working at all???
Who's name is on the car title and insurance that he is driving?

If he gets in a wreck, is drunk - pray he doesn't kill or injure anyone - because if it is your name on those ???
Something to think about

You will never have a chance to meet someone new with him staying there.

He is manipulating you and using you & you know it - but I don't know what to tell you to get him to move on.
- but as long as you give him money and feed him and let him sleep in the same place why would he leave???

I hope you aren't riding in the car with him when he is drunk!
