from now on I write the chords resulting from the bass 
and guitar part together.
Bass plays G A Bb C, guitar keeps arpeggiating on Gm 
3553xx (or 3103xx?).

Gm Am Bb           Cm             Gm Am Bb          
        Countless times I trusted you,    I let you 
Cm
back in
        Gm         Am       Bb             Cm         
        Knowing... yearning... you know I should have 
        Gm Am Bb    Cm
run but I, I stayed

Gm F Cm          Bb     Gm       F
        Maybe I always knew
     Cm             Bb             Gm  F  Cm  Bb      
        My fragile dreams would be broken for you
Gm F Cm Bb


Gm Am Bb        Cm           Gm  Am           Bb     
        Today I introduced myself  to my own feelings
     Cm

     Gm           Am    Bb                 Cm         
        In silent agony,  after all these years, they 
           Gm Am Bb                 Cm
spoke to me...      after all these years

Gm F Cm          Bb     Gm       F

     Cm             Bb             Gm  F  Cm  Bb      
        My fragile dreams would be broken for you

in the instrumental part, "Gm" means to alternate Gm 
and Gsus4, while
                          "Eb"  ...  ..    ...    Eb ...  

Eb6.

Gsus4 is 355533, Eb6 is x65543.

playing the song with a capo on the 3rd fret makes it 
easier.

the guitar riff is essentially made of two slighly 
different repeating figures:

:----------------------:
:-----------3-----3----:
:.-5----3-5---3-----3-.: over Gm
:.--------------------.:
:----------------------:
:----------------------:

:----------------------:
:-----------3-----3----:
:.-5----3-5---------3-.: over Eb and Cm
:.------------5-------.:
:----------------------:
:----------------------:

the only relevant variation, played over the F chord:

:----------------------:
:----------------------:
:--5-3-2----5-3-2------:
:--------5--------5-3--:
:----------------------:
