There aren't any magic words. It doesn't matter whose words you use. No matter how good they sound to us, all the alcoholic can see is the tiny confines of their world with alcohol. And they can't imagine it any different. He probably DOES love you (to the extent he can), but he can LIVE WITHOUT you more easily than he can live without alcohol.
The co-founders of AA discovered that the only words that sink in with an alcoholic are those of someone else who has been exactly where they are. And only when the the alcoholic is ready to hear them.
