It might be because it's a huge earworm for me lately, but I think it also fits this situation. "If I Fell" by the Beatles the definitive Bones pining after Kirk song.

"If I Fell"

If I fell in love with you
Would you promise to be true
And help me understand
'cause I've been in love before
And I found that love was more
Than just holding hands

If I give my heart to you
I must be sure
From the very start
That you would love me more than her

If I trust in you, oh please
Don't run and hide
If I love you too, oh please
Don't hurt my pride like her
'cause I couldn't stand the pain
And I would be sad if our new love was in vain

So I hope you see that I
Would love to love you
And that she will cry
When she learns we are two
cause I couldn't stand the pain
and I would be sad if our new love was in vain

so I hope you see that I
would love to love you
and that she will cry when she learns we are two.

If I fell in love with you
