Help please

I can not identify this song. I only remember some parts ofit. "To find a girl? as beautiful as you.....................can you forgive me I I I I I I I L O O O O VE YOU; IIIIIIIII LOOOOOOOVE YOU................

It`s a romantic song from the 80s (i think) the video is about the band taping the song in a recording studio. And one of the guys that is working there remembers his discussion with his wife.. And at the end of the song his wife goes to the studio with their daughter. And the vocalist licks his own finger (not in a inappropiate way)

I SHOULD HAVE KNOWN BETTER by Jim Diamond 1984 ???????

And I shoulda known better
To lie to one as beautiful as you
Yeah, I should have known better
To take a chance on ever losing you
But I thought you'd understand
Can you forgive me

I saw you walking by the other day
I know that you saw me, you turned away
And I was lost
You see, I've never loved no one as much as you
I've fooled around but tell me now just who is hurting who

And I should have known better
To lie to one as beautiful as you
Yeah, I should have known better
To take a chance on ever losing you
But I thought you'd understand
Can you forgive me

I-I-I-I-I-I-I-I-I-I
Shoulda known better
I-I-I-I-I-I-I-I-I-I
Shoulda known better

It's true, I took our love for granted all along
And trying to explain where I went wrong
I just don't know
I cry but tears don't seem to help me carry on
Now there is no chance you'll come back home, got too much pride

And I should have known better
To lie to one as beautiful as you
Yeah, I should have known better
To take a chance on ever losing you
But I thought you'd understand
Can you forgive me
Ughh
I-I-I-I-I-I-I-I-I-I love you
I-I-I-I-I-I-I-I-I-I-I love you

No-no-no-no-no-no I love you
No-no-no-no-no-no, yeah
And I should have known better
To lie to one as beautiful as you
