I knew it was there
Though I tried to hide it
The feeling just kept on shining through
Haven't known you that long
So I try to deny it
But the feeling was much too
Much too strong
Could this be love
Deep down inside
Tearing me apart
I feel it in my heart
Constantly, you're on my mind
Thinking about you all the time
I can't sleep no matter what I do
I just keep on thinking 'bout you
Why do I feel this way
When I know you have someone
That you're seeing each and everyday
Should I play this game
Of just being your friend
When I know that's not where I want it to end
How could this be wrong
When it feels so strong
Tearing me apart
I feel it in my heart
Constantly, you're on my mind
Thinking about you all the time
I can't sleep no matter what I do
I just keep on thinking 'bout you
No I don't want to start
No trouble
Between you and I and you lover
But I must tell you what I'm going through
Everytime you walk by
I see love in your eyes
You're on my mind
Keep on thinking about you love
I can't sleep
I just keep on thinking 'bout you
Constantly, you're on my mind
Thinking about you all the time
I can't sleep no matter what I do
I just keep on thinking 'bout you
