Love is the key to successful marriage: Antonio Banderas

London: Spanish actor Antonio Banderas says he and wife Melanie Griffith have opened up to the possibility of falling in love with each other again and again. The `Mask of Zorro` star, who has been married to the actress since 1996, said despite going through some tough times they have managed to keep their marriage alive. "The secret to our marriage is as complicated and as simple: we love each other. We`ve gone past that first intoxicating rush of love, and we`ve stayed on the path through crises and difficulties, and now we`ve opened up to the possibility of falling in love with each other again and again," Banderas said. The actor said the couple endured their toughest time in 2009, when Griffith sought treatment for addiction to prescription drugs. "We went through a lot of trouble. Melanie was addicted. But the whole family came together for her, for the mother. And she did very well," he added. PTI
