Hi! I've figured out both the chords and the tab so , here! Try it ,
It's very easy

Verse:
I've been cheated on you since i dont know when
D                                          G

So I made up my mind it must come to an end
D                                       G

Look at me now, will I ever learn
D               D6

I dont know how, but I suddenly lose controll
D               D6              G

Theres a fire within my soul
                  A

Just one look and I can here a bell ring
G    D   A

One more look and I forget everything , oh oh
G   D    A

Chorus:
Mamma mia here I go again ,my,my, how can i resist you?
D                       G  C  G

Mamma mia does it really show again,my,my, just how much I've missed you
D                                 G C  G

Yes , I've been broken hearted, blue since the day we parted
D               A              Bm

  Why,why, did i ever let you go, Mamma mia, now i really know
G C   G    Em        A        D               Bm

  My,my I could never let you go
G C  G   Em           A        D

Do like in the verse and then this chorus:

Even If I say bye-bye, leave me now or never
Bm           G C  G     Em             A

Mamma mia It's a game we play
D           Bm

  Bye-bye, doesn't mean for ever
G C   G    Em            A     D

Mamma mia, now i really know
D          Bm               G


My,my I could never let you go
C  G   Em           A       D
