jimmy please say you'll wait for me

I'd like to know who sings this song(and the artist), the chorus goes:

Jimmy please say you'll wait for me
I'll grow up someday you'll see
saving all my kisses just for you
signed with love forever true

And he replies back

?? please don't cry
You'll forget me by and by
You're just 16 I,m 22
and ? i just can't marry you
Thanks in advance!!

I think it's a country song?

Conway Twitty - "Don't Cry Joni"

thanks!!!
