Ditto what everyone else is saying. You aren't responsible for him, he is an adult and should be able to take care of himself.
It sounds like you're taking care of yourself - that's great. I know this is hard. I wish it wasn't but it is.
On another note, I liked "Across the Universe". Not entirely, but I thought it was a fun re-versioning of the songs. I entirely agree with you that some songs worked and others didn't.
Okay, so now that I know your thought on that movie, what about the songs in "I Am Sam"?
