Original tekst - Engleski - My constant love

It´s for my ex-fiance(a woman). She´s returning home, far away for personal reasons, so I need to put this on two rings. But later i´ll see which part goes in what ring. I hope you can help me.
Besides this was written on spanish but i figure out there would be more english - latin translators than espanish - latin.
Thank for the suggestion chronotribe. As you´ll see i changed the text.
