[Chorus:]
I warned myself that I shouldn't play with fire
But I can tell that I'll do it one more time
Don't trust in myself, (Mmm) no good for my health (Mmm)
You messed with my heart, now you're the reason why.

[Verse 1:]
Do you remember when you told me I don't have to worry?
"He's overseas, out on his tour, he'll be okay without me"
You said you had nothing to hide, that you left him long ago
I shoulda known that was a lie.

[Chorus:]
I warned myself that I shouldn't play with fire
But I can tell that I'll do it one more time
Don't trust in myself, (Mmm) no good for my health (Mmm)
You messed with my heart, now you're the reason why
I warned myself that I shouldn't play with fire
But I can tell that I'll do it one more time
Don't trust in myself, (Mmm) no good for my health (Mmm)
You messed with my heart, now you're the reason why.

[Verse 2:]
Do you remember when you said, "Do not tell anybody
'Cause if ya do, I'll be the first to put my hands around your thr—"?
If you had nothing to hide, why is no one s'posed to know?
I shoulda know that was a lie.

[Chorus:]
I warned myself that I shouldn't play with fire
But I can tell that I'll do it one more time
Don't trust in myself, (Mmm) no good for my health (Mmm)
You messed with my heart, now you're the reason why
I warned myself that I shouldn't play with fire
But I can tell that I'll do it one more time
Don't trust in myself, (Mmm) no good for my health (Mmm)
You messed with my heart, now you're the reason why.

[Outro:]
The reason why
