Breaking Up Is Hard To Do

Don't take your love away from me

Don't you leave my heart in misery

If you go then I'll be blue

'Cause breaking up his hard to do



Remember when you held me tight

And you kissed me and it felt so right

Think of all that we've been through

Breaking Up Is Hard To Do



They say that breaking up is hard to do

Now I know, I know that it's true

Don't say that this is the end

Instead of breaking up I wish that we were making up again

We were making up again



I beg of you

Don't say goodbye

Can't we give our love just one more try

Come on baby, let's start a new

'Cause breaking up is hard to do
