Constantly lyrics

I knew it was there
Though I tried to hide it
But 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

[Chorus:]
Constantly, you're on my mind
Thinking 'bout 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 every day
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 the feeling's so strong
Tearing me apart
I feel it in my heart

[Chorus:] [2x]
Constantly, you're on my mind
Thinking 'bout 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 your lover
But I must tell you what I'm going through
Everytime you walk by I see love in your eye

You're on my mind
Keep thinkin' about your love
I just keep on thinking 'bout you

[Chorus:]
Constantly, you're on my mind
Thinking 'bout you all the time
I can't sleep no matter what I do
I just keep on thinking 'bout you
