I see you've been crying, no reason for lying to me  'Cause I've seen you smiling when you were living with me  You're not happy with her  You're not happy with her    You're living with her now but still you are living alone  You're feeling sorry, you want me to take you back home  You're not happy with her  You're not happy with her at all  Forgive me asking you    Who let the heartache in?  Who let the tears begin?  Who let the pain walk in?  Who let the heartache in? (It was you)    Who let the heartache in? (It was you)  Who let the tears begin? (It was you)  Who let the pain walk in?  It was you, only you    You're feeling lonely, your heart's feeling empty and cold  And you only want me because you have no-one to hold  You're not happy with her  You're not happy with her at all  Forgive me asking you    Who let the heartache in?  Who let the tears begin?  Who let the pain walk in?  Who let the heartache in? (It was you)    Who let the heartache in? (It was you)  Who let the tears begin? (It was you)  Who let the pain walk in?  It was you, only you    We should have stayed together  Now my love is gone forever, ever    Who let the heartache in?  Who let the tears begin?  Who let the pain walk in?  Who let the heartache in? (It was you)    Who let the heartache in? (It was you)  Who let the tears begin? (It was you)  Who let the pain walk in?  It was you, only you    Who let the heartache in? (It was you)  Who let the tears begin? (It was you)  Who let the pain walk in?  It was you, only you    Who let the heartache in? (It was you)  Who let the tears begin? (It was you)  Who let the pain walk in?  It was you, only you    Who let the heartache in? (It was you)
