I read this song as the singer having cheated or done something otherwise questionable in a relationship that truly hurt his significant other. However he legitimately does not feel bad even though he knows he should (meaning the relationship needs to end).
I wish I could cry on demand
Boo-hoo, boo-hoo
Given all these troubles on my mind
The tears won't come out
I've been shaking
Shaking in my boots
Every time I hear my telephone
Ring, it can't possibly by you
You never call
Not since my little accident
I didn't mean to cause any trouble
I didn't know you were so serious, and
I didn't mean to burst our bubble
It can only float for so long
Now I realize, I realize that you were wrong
'Cause what happens in Vegas don't take very long
To travel cross continents and onwards overseas
On to our little island, to our city, our home, but
I didn't mean to cause any trouble
I didn't know you were so serious, and
I didn't mean to burst our bubble
It could only float for so long
Sometimes I wish I could cry on demand
Boo-hoo, boo-hoo
Given all these troubles on my mind
The tears won't come out
I didn't mean to cause any trouble
I didn't know you were so serious, and
I didn't mean to burst our bubble
It could only float for so long
Sometimes I wish I could cry on demand
Boo-hoo, boo-hoo
Given all these troubles on my mind
The tears won't come out
I wish I could cry on demand
Boo-hoo, boo-hoo
Given all these troubles on my mind
The tears won't come out
The tears won't come out
The tears won't come out
