I understood a spanish sentence without looking it up!!!

A lady on a movie said in spanish, "Thank you, my love. You have changed my life."

All I caught was, "Gracias, mi amor." And then, "cambiaste" and "vida". There were some other small words in there, so I know it must have been, "Gracias, mi amor. Cambiaste mi vida" or "Tu cambiaste mi vida".
