I'm happy you're happy, But are you really? Cause all that I see Is heartache behind your smile I'm happy you're happy You never thought you would be And if they knew the story, Then they'd be unhappy too Cause I don't know where to go When you're looking at me I don't know what to say When you never believed in it You never believed in it And I don't know which side to take When we both made mistakes Betting who's gonna break By the end of the day for it Don't wanna wait for it I didn't think I'd ever let you go So now I don't know how to let you know I'm happier than I used to be I'm happier than you were with me I didn't think I'd ever let you go And now I don't know how to let you know I'm happier than I used to be I'm happier than you were with me Cause I don't know where to go When you're looking at me I don't know what to say When you never believed in it You never believed in it And I don't know which side to take When we both made mistakes Betting who's gonna break By the end of the day for it Don't wanna wait for it You didn't heal Lost yourself in your feelings Been calling me And you're stuck on believing that I'll someday take you back But this is real It's been years of repeating I didn't plan for all these years of your reeling now And all on my account Cause I don't know where to go When you're looking at me I don't know what to say When you never believed in it You never believed in it And I don't know which side to take When we both made mistakes Betting who's gonna break By the end of the day for it Don't wanna wait for it I'm happy you're happy But are you really? Cause all that I see Is heartache behind your smile I'm happy you're happy (I didn't think I'd ever let you go) You never thought you would be (And now I don't know how to let you know) And if they knew the story (I'm happier than I used to be) Then they'd be unhappy too I'm happier than I used to be
