chic, let HIM sit with the discomfort too. Don't put it all on yourself. It's your house, YOU are paying the bills and SUPPORTING his butt. He is eligible for a free no frills cell phone for emergencies and limited texting. If he wants a phone, let him get this for himself instead of you footing the bill. Same for cigarettes (I don't remember if you support this too, so excuse me if I am wrong).
you stated the facts and requirements. Either he steps up to the plate or he can be spending time on the public computer at the library (they will give him 30 mins I think).
and yes, get out of the house...do you want me to send Sammy to you? he loves cats and loves to go for a walk, he doesn't drag you but sniffs a lot.
