Hmm. This is tougher than it seems, because what type of lyrics is she looking for? I'd just like to say that I may not *like* these songs

but they are pretty sappy, at times.
I found an article here:
http://www.canoe.ca/JamMusic/feb11_love-sun.html about love songs, as well. It lists a whole bunch.
Or try
http://www.cdnow.com and look up 'love' or 'romantic' or 'ballads'.
Dido: Here with Me
I won't go, I won't sleep, I can't breathe, until you're resting here with me
I won't leave, I can't hide, I cannot be, until you're resting here with me
Coldplay: Yellow
You know, you know I love you so,
You know I love you so.
Look at the stars,
Look how they shine for you,
And all the things that you do.
Whitney Houston: I Will Always Love You
If I should stay
I would only be in your way
So I'll go but I know
I'll think of you every step of the way
I will always love you
I will always love you
My Heart Will Go On: Celine Dion
Love was when I loved you, one true time I hold to.
In my life we'll always go on.
Near, far, wherever you are,
I believe that the heart does go on.
Iris: Goo Goo Dolls
And I'd give up forever to touch you
'Cause I know that you feel me somehow
You're the closest to heaven that I'll ever be
And I don't want to go home right now
In Your Eyes: Peter Gabriel
in your eyes
the light the heat
in your eyes
I am complete
in your eyes
I see the doorway to a thousand churches
in your eyes
the resolution of all the fruitless searches
in your eyes
I see the light and the heat
in your eyes
oh, I want to be that complete
I want to touch the light
the heat I see in your eyes
Leaving on a Jet Plane: John Denver
So kiss me and smile for me, tell me that you'll wait for me,
Hold me like you'll never let me go.
I'm leaving on a jet plane, don't know when I'll be back again.
Oh, babe, I hate to go.
