When is enough, enough?

So I had a pt who decided he was going to Missouri I mentioned this is on a previous post. I arranged his transportation there, I got him home care there, I got him a primary doctor there, I tracked down his brother's contact info and let him use my cell phone to call. Finally, I helped him pack and put him in a taxi. I received a phone call from him, although when we sent him to Missouri we gave him 2 weeks worth of prescriptions as well as any leftover meds. Evidently, that wasn't good enough b/c he is in Missouri and he can't access his meds there. Somehow that was all my fault. Oy.
In terms of my dating life I've been talking to a guy from Frumster. I discovered that we had met before. At one point I was at a game night and met him there when he was super obnoxious and nasty and moved my chair so I was now sitting half on the carpet half on the floor. I called a spade a spade and went wow you really are an ass. Somehow I do not think this would be a good match considering most of my friends see him as a moocher. I don't deal well with moochers. Oy. So far I'm not returning calls and no longer have access to him on facebook so I can tell him its not going to work.
