yes i think so. i do agree that true love can happen again. However, i have to say that I do not believe in the kind of love that they showed between SRK and rani in the movie "kabhi alvida na kehna".
But if a spouse dies or divorces, I do think their partners can find true love again
True love can and does come more than once in a lifetime. Sometimes circumstances arise in life where your previous love either withers off or meets an untimely end. And you have to find new avenues in life.
