Is this the song?
If I give my heart to you
Will you handle it with care
Will you always treat me tenderly
And in every way be fair
If I give my heart to you
Will you give me all your love
Will you swear that you'll be true to me
By the light that shines above
And will you sigh with me when I'm sad
Smile with me when I'm glad
And always be as you are with me tonight
Think it over and be sure
Please don't answer till you do
When you promise all those things to me
Then I'll give my heart to you
And will you sigh with me when I'm sad
Smile with me when I'm glad
And always be as you are with me tonight
Think it over and be sure
Please don't answer till you do
When you promise all those things to me
Then I'll give my heart to you
Wikipedia article on 'If I Give My Heart to You'I'm fairly sure the song your thinking of was sung by Margo Smith in 1979, it fits the timeline anyway.
Or was it this one sung by George Strait?
At a table for two
With candle light and wine
That diamond burnin' holes in his pockets
Thinkin' now is the perfect time
When he popped the question he could see
The teardrops fill her eyes
She said I knew this was commin' and I am sorry
But I hpe you realize
You can't make a heart love sombody
You can tell it what to do
But it won't at all
You can't make a heart love sombody
You can lead a heart to love
But you can't make it fall
Then she reached for his hand
And said I want you to know
I've done everything that I know of
To make this feeling frow
I've begged and ;leaded with my heart
But there's no gettin' through
My heart's the only part of me
That's not in love with you
