Can someone translate this sentence please

esy eisai pou moy eklepses mia mera thn kardia moy kai apotote ginonte aliuina ola ta oneira moy

The Google translator tool thinks it's Italian :-)

Many thanks!

εσυ εισαι που μου έκλεψες μια μέρα την καρδιά μου και απο τοτε γίνονται αληθινά όλα τα ονειρα μου

Thank you very much :-)

Google translate doesn't work well with this. So:

"You are the one who stole my heart one day and since then all my dreams come true."

Nai... much better than what I got from Google... :-)
Thank you <3
