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 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

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
Every time you walk by, I see love in your eyes
