It's not unusual for people to drop out for one reason or another. 

Start looking for a replacement to finish the job, because that is where this relationship is heading.As a side note - unless the job is extremely large (more than 400 sheets) or very unusual (lots of odd-angled intersections, curved surfaces, etc.) no drywall job should take longer than about 2 weeks at the outside top end of scheduling.
