Gotta Dance Waltz in Tragic situation :(

Hi people out there, guys i need really a very nice Romantic but Very Tragic Song for Waltz. I gotta do "Spot Ligh Dance" with a lady in a party where my Girl would also be present. we broke up so tragically that i shake my head in utter dismay and sorrow, none of my or her fault. i gotta give her this message through this dance "This Dance is for you and I will always Miss you Girl, whatever". I hope u people understand the situation NOW. plz reply very soooonnn
I tried instrumental by Zamfir on Pan Flute Love Theme "Love Story-Where Do I Begin" but its too fast 1...2/3 does not set... so some thing like this
Thanx

What about this version of "Bring me to life". To me it sounds very tragic, but it's slow for a waltz but possible.
