the song in my head for a good 3 days now

IF I FELL
(Lennon/McCartney)

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
