I Wouldn't Know Where To Begin

There's someone else you've fallen for and I know it
You don't love me anymore and you show it
You're saying things like here's where I came in
I wish that I could be laughin' forget it all and start anew
But I wouldn't know where to begin

I stopped looking for the other the day I met you
Friends told me what you wouldn't do and yet I'd let you
Now they're saying things to me like to start again
But they don't understand that I can only love one man
And I wouldn't know where to begin
