I agree with Pelican. His getting a job does not have to mean living with you. And if it comes down to that choice, then I firmly believe getting sober is more important than taking the job. Yes, even in this economy, and even with the imminent birth of a child. Putting his recovery on hold for temporary immediate financial gain is a recipe for disaster.
I think it would be wise to continue in your own best interests and the best interests of your baby and let him sort his life and employment out by himself.
This is my perspective using the 20/20 hindsight of having been married to an alcoholic for 20 years and having two children with him.
