On a serious note
Sit him down
Tell him
To Learn some respect or get the hell out
To do something with his ***, get a job or something, or get the hell out
To start paying some bills or get the hell out
To start buying his own **** food or get the hell out
Sit down and tell him what's up, he used to be one of your boys so you should at least have it in you to tell him. Should he not comply, kick him out.
If he wants problems, dont fight him(unless he's in your house, then do what you MUST) - - - call the cops, have him taken off and have his shit ready for picup
