Lou, I totally agree w/what Sotto posted. You have to remember that he's not on the same timescale that you are. His clock is very, very slow and it took years for him to go into crisis and it will take a while for him to come out the other end. Therapy is helping him and I hope he remains committed to working on himself.
For now, keep the focus on you and what you need to do to find a new place and a new job.
Take care!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
