oldish country song! please help me!!!

ok so i can't really remember a whole lot of the lyrics BUT some of them are

"i should have said i loved you but i didnt have the chance"

"you (or she) walked away"

and at the very beginning of the song he's singing about finding a box full of letters

its a male singing, and i know its not a band, its one single guy....if anyone can help me that would be great!! thanks so much!!

I did not find a country song (yet). The following songs contain some of the lyrics you're looking for.

"Was It Something I Didn't Say" by 98 Degrees

I should have told you how I felt then
Instead, I kept it to myself, yeah
I let my love go unexpressed
'Til it was too late
You walked away


"Lie To Me" by Bryan Adams

"Without You" by Howie Day (ft. John Mayer)
