The roller coaster ride is continuing.....this time on a downward turn.  T had 5 days of coming home at a reasonable hour, he was more pleasant than he had been....he offered and helped me with the groceries, we talked, we laughed, we seem to have connected, and then.......he didn't come home last night.  Walked in the door at noon as if nothing was wrong.  I think he's using cocaine.  He had a bloody nose, said he hasn't slept the last few nights, has circles under his eyes, and complained about his heart.  Not looking good......
