From the details you have posted it appears that the clutch friction plate has broken up hence no drive.
Can you get any drive if you put the car in first gear then try (with great care and be ready to turn off engine if it starts)to start the car, if it leaps forward then the clutch may be okay and you may have a problem with your gearbox.
If clutch is at fault replace clutch plate , cover and release bearing.
