need desperately this song title

i first heard this song in the late 80s and i loved it, i thought it's a cliff richard's song, but i've been looking up for the title for a long time and i just couldn't find it. please,can anyone help me, what's the name of it and the singer?the lyrics go more or less this way:

"just because i love you so..... i'd do anything you want me to, if you stay with me forever ,won't you stay with me for all time.....stay with me forever and ever cos' i love you ,i'll give you everything tonight...''

My wild guess is "Together Forever" by Shai

If you say that you love me
Won't you stay with me for all time
Because your smile
It is what keeps me going
Through all the hard times
Yes it does

And we'll be together forever
again
We'll be together forever
Just you and me
