Letra de A change of heart

Well i guess you must have had a change of heart
you don't treat me like you used to at the start
your campaign of love was quite a work of art
but i guess you must have had a change of heart
Guess i took too much for granted anyway
but it's just cause i'd believe the things you'd say
not so long ago you'd swore we'd never part
but i guess you must have had a change of heart
Well goodbye to all those castles in the air
and goodbye to all the dreams we used to share
they were fragments of a dream that fell apart
now they're gone because you've had a change of heart
