From the 70s, but I think it would fit real well

"I'm Not In Love" by 10CC

I'm not in love
So don't forget it
It's just a silly phase I'm going through
And just because
I call you up
Don't get me wrong, don't think you've got it made
I'm not in love, no no, it's because..

I like to see you
But then again
That doesn't mean you mean that much to me
So if I call you
Don't make a fuss
Don't tell your friends about the two of us
I'm not in love, no no, it's because..

I keep your picture
Upon the wall
It hides a nasty stain that's lying there
So don't you ask me
To give it back
I know you know it doesn't mean that much to me
I'm not in love, no no, it's because..

Ooh you'll wait a long time for me
Ooh you'll wait a long time
Ooh you'll wait a long time for me
Ooh you'll wait a long time

I'm not in love
So don't forget it
It's just a silly phase I'm going through
And just because I call you up
Don't get me wrong, don't think you've got it made
I'm not in love
I'm not in love
