I had the chords written out and decided that if nobody else had I would post them 
here. The other version misses out some important aspects of the songs harmony imo 
which is why I decided to submit mine. Tried to get the chords in the right place 
above the lyrics the best I could, hope this helps.

Verse 1:
A                                     F#m
I never know if you're serious
A                                     F#m
It's all so vague and mysterious
With me and you
Bm                                           E7
Just when I think we're on solid ground
Bm                                           E7
You pull the rug out and knock me down 
 
Verse 2:
A                                     F#m
Are you just trying to play with me?
A                                     F#m
Do you get joy from my misery?
I'd like to think
Bm                                           E7
It's just a phase and we'll work it out
Bm                                           E7
But you keep jerking my heart around
 
Chorus:
          A                                               C#
Now I've caught a classic case of love whiplash
         F#m                                        D
You push me off and then you pull me back
 A                                                      C#
Please could you tell me if you're being sincere
          F#m                                        D
Cause darlin' I can't stand to cry another tear
 
Verse 3:
Amaj7                               F#m7
I'm losing count of the damages
Amaj7                              F#m7
My heart is covered in bandages, it's what you do
Bm7                                    E
I'm not so hard to accommodate
Bm7                                    E
Just get a clue or get on your way 
 
Chorus:
 A                                               C#
Now I've caught a classic case of love whiplash
         F#m                                        D
You push me off and then you pull me back
 A                                                      C#
Please could you tell me if you're being sincere
          F#m                                        D
Cause darlin' I can't stand to cry another tear

Bridge:
Bm                                                   D
It's not a long conversation
                         F#m                       E           Bm
Don't want to waste all your precious time 
Bm                                             
It's not a difficult equation 
    D                                       E7
A simple yes or no will do fine 
 
Chorus:
             A                      C#                        F#m
Cause I've got a bad case of love whiplash
                       D
Ohhhhhh Ohhhhhh
           A                           C#                         F#m
Now I've caught a bad case of love whiplash 
           D7
Yeah, now, now, now,
 
Chorus/Outro:
        A                                                C#
Now I've caught a classic case of love whiplash
          F#m                                         D
You broke my heart and now you want it back
A                                                         C#
Please could you tell me if you're being sincere
             F#m                                         D
Cause darlin' I can't stand to cry another tear
 
          A                                 C#                    F#m          D
Now I've caught a bad case of love whiplash, oh, oh
         A                                 C#                    F#      
Now I've caught a bad case of love whiplash!
D                                        A
mmmmmm, mmmmm mm
