Constantly

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 a friend?
When I know that's not where I want it to end

How could this be wrong?
When the feeling's so strong
Tearing me apart
I feel it in my heart

No I don't want to start no trouble
Between you and I and your lover
But I must tell you what I'm going through
Everytime you walk by I see love in your eyes
