I did an acoustic cover of this song and the chords were requested. 
My cover was semi improvised so I used different chords progressions for the 
bridges and stuff but this is right for Nevertheless' version.
Enjoy.

The chords are as follows:

   E (E)F#m A C#m B E/D#
e|-0--0--2--0--0--0--0--|
B|-0--0--2--0--5--0--0--|
G|-1--9--2--2--6--4--8--|
D|-2--9--4--2--6--4--9--|
A|-2--7--4--0--4--2--7--|
E|-0--0--2--x--x--x--x--|

A
I haven't reached perfection
C#m                  B
But is that what she needs? 
A                             
I haven't reached the wisdom 
C#m                     B
That she should always heed
     A
And I am just a man
C#m                 B             
I haven't died for her, but I would. 
C#m              B
I'll do whatever I have to

E  F#m    A       C#m     B     A 
I may not be her perfect chemistry,
E        F#m   A                C#m         B       A   
But, if I can love her like You do, that's all she needs

E

A                         C#m                      B           
I haven't found the remedy to every tear she'll cry
                C#m               A
But I'll try to be the one who's by her side

E   F#m    A      C#m     B     A  
I may not be her perfect chemistry,
E       F#m    A                C#m         B       A   
But, if I can love her like You do, that's all she needs
