If your student is still showing no progress, then sit him down, give him an honest assessment and tell him you can't keep taking his money and that he should consider another career. Maybe you can suggest he start flying RC airplanes which may help him figure everything out. One of my sharpest students came to me with over 5 years of RC experience and I solo'd him in 5.5 hours.
