Reggaeton song...

Ok i had a friend play this mixtape cd at my house, he sang me this song and i fell in love with it, only problem is. I dont speak spanish so i cant identify with the words, i know the chorus goes along to Leaving On A Jet Plane, And it starts out with a telephone call about how this guy is leaving, he's telling his girl that if he doesnt come back he loves her and always will... please some one help im losing my mind trying to find it and since my friend and i no longer speak i cant ask him
