If I Only Knew

If I only knew how much I′d miss you I'd never say bye bye bye
Cause now I find I can′t forget you although I tried tried tried
I made a big mistake to leave you that's why I cry cry cry
If I only knew you'd miss me too I′d never say bye bye bye
(If I only knew how much I′d miss you) I'd never say bye bye bye
(Cause now I find I can′t forget you) although I try try try
(I made a big mistake to leave you) that's why I cry cry cry
(If I only knew you′d miss me too I'd never say bye bye bye)
If I only knew how much I′d miss you...
