So I saw some other guy's tab, and he was saying how his was the most accurate, and the 
other previous poster basically didn't have ears.
Needless to say, THIS is the closest version to the song. Enjoy.

D (xx0232@1)                 A (x02220@1)                  Bm (x24432@1)     
         GI've (320003@1)been waiting for months, waiting for years, waiting for you to change.
                D (xx0232@1)                            AAw, (x02220@1)but there ain't much that's dumber, there ain't much that's dumber
        G (320003@1)                    Athan (x02220@1)pinning your hopes on a change in another.
    D (xx0232@1)               A (x02220@1)     Bm (x24432@1)                   GAnd (320003@1)I, yeah I still need you, but what good's that gonna do?
    D (xx0232@1)     A (x02220@1)              G--               DNeeding (xx0232@1)is one thing, and getting, getting's another.

(Same stuff for the rest of the song.)

So I been sitting around, wasting my time,
wondering what you've been doing.
Aw, and it ain't real forgiving, it ain't real forgiving
sitting here picturing someone else living.
And I, yeah I still need you, but what good's that gonna do?
Needing is one thing, and getting, getting's another.

I've been hoping for months, hoping for years, hoping I might forget.
Aw, but it don't get much dumber, it don't get much dumber
than trying to forget a girl when you love her.
And I, yeah I still need you, but what good's that gonna do?
