WHY should I have to pay a upgrade fee just TO see WHO likes ME, I was told this site was totally free with out hidden fee,s

You don't, of course.

That is a feature on the upgrade, to jump the gun
on MutualMatches, and see who said 'Yes' to your
profile without having to return the favor first
by clicking 'Yes' on their profile.

Which then automatically shows you who it is.
As you have selected each other.
Which is the point.

It is like seeing every woman you pass on the street
with a sign on them saying, 'yes, I already like you'
rather than having to go any deeper.

Your choice.
