Same chords all through the song. Pretty simple.

Verse 1
                                 BmajThere's (x2444x@1)clothes all over the floor
                                  Dmajdon't (xx0232@1)remember them being here before
                       Gmaj (320003@1)                       AmajSmell (x02220@1)of perfume isn't here, why's lipstick on the mirror
                        EmajAnd (022100@1)still I don't understand

Verse 2
No pictures left in the hall
There's three new holes in my wall
Where the hell's my credit cards, why's my wallet in the yard
Still I don't understand

Chorus
Well now I guess I should've listened
When you said you'd had enough
A little trick I picked up from my father, in one ear and out the other
Why's love gotta be so tough?

Verse 3
Should see the look on my face
My shit's all over the place
Why's this happenin to me, why'd you take both sets of keys
And still I don't understand


Chorus


And now I guess I should've listened
(bridge)


Verse 4
There's clothes all over the floor
don't remember them being here before
There are no candles in here, lipstick's still on my mirror
And still I don't understand
