Since we've been together
Everyone's been telling me
There's been a change in my behavior
I wonder what's come over me

And I kept telling myself I wasn't lonely
Wouldn't get serious with no one else
And maybe I was afraid of what might happen
But that's all in the past and it's all because of you

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

Now as I view the situation
I have come to realize
I've run out of reasons
It's something that I just can't hide

When I lose my direction
I'll only have to think of me and you
And then it all comes back together
And I realize that it's all because of you

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

So in love with you
(I'm so in love with you
I just don't know what I'm doing)
So in love with you
(All in the things that you do for me, baby)
So in love with you
(Can't take my eyes off you, baby)
All because of you

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

Guess it must be love
Guess it must be love
Guess it must be love
Guess it must be love

Oh baby, I just wanna tell you the way you make me feel
I've never had anybody to just just hold me the way you do

It must be love
It must be love
It must be love
It must be love

I hope you don't mind me talkin' to you like this
You make me feel so good
You mean the world to me
All because of you

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

Guess it must be love
Guess it must be love
All in the things that you do for me
Guess it must be love

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

I guess it must be love
All in the things that you do for me
I guess it must be love
'Cause you mean the world to me

Guess it must be love
Guess it must be love
Guess it must be love
Guess it must be love

Guess it must be love
Guess it must be love
Guess it must be love
Guess it must be love

Guess it must be love
Guess it must be love
