karengog, it sounds to me like you have enough experience to know that the clutch mechanism is working.
So, my assumption is that the clutch discs are just stuck together from setting/corrosion.
What should work to break everything free is to simply ride the bike in low gear with the clutch pulled in.
NOTE: On a back road, and using care..
With the bike running, get someone to help you push it as fast as possible, and (at idle) engage first gear.
Once bike is in gear, do moderate to hard accells and decells with the clutch pulled in.
Should come loose pretty quickly.
Be careful! Ride safe, Ted
