clutch stopped slipping

What is your question?

So clutch has started slipping a week ago and gotten progressively worse (less acceleration and more revving day by day, I drive a lot) until today where the car would barely move and I sounded like I was going in neutral. However suddenly my car no longer experienced any slipping. The question is, do I still need to replace the clutch (will I damage flywheel/pressure plate if I don't) or did I just go through a glazed layer? I did some online research and those are the two outcomes I saw that were possible.

How long has your 2002 BMW 330Ci had this problem?
