I would go to the landlord myself and explain that in 2 months you will be able to be on your own, and the baby etc... just leave the guy out of the picture for right now?
I hate to suggest this... but are you SURE he's going to work? If so, do they realize he has a baby on the way? Maybe that will help the employer cut his checks?
Yes, black and white thinking doesn't allow you to see any grey, and there is grey here... murky sometimes but it's here.
I agree with freewill... breathe..... try and do some calming... this isn't the end of the world, though we all feel what you are telling us, the upset and worry...

It might be another glitch in the path, you know?
