More likely the clutch is dragging from air in the slave cylinder or the pilot shaft bearing is dragging.

The reverse gears are turning when they shouldn't, and there is no synchornizer on reverse as a general rule -- it's VERY unlikely you would want to engage reverse while moving!

Also possible the pressure plate spring is bad, causing the clutch to fail to release completely.
