sorry he quit his job cinder, but i think that you are right to not feel obligated to give him a ride or anything else, the way that you are handling him right now, may just be what it takes for him to get sick of himself and his life. i'm cheering you on and praying for you both at the same time. i believe that he'll get it soon, but its how long you are willing to wait.
the waiting took on a whole new meaning for me once i learned how to love my life with or without him. didn't think of it as waiting any more and that was so liberating.
