It’s a matter of heart, All Marriages are the highest point of contract or agreement or promise each makes – stating “Only death can depart us”. Now there are possibilities of one of them leaving the other due to various reasons. In your assumption if one of them have died then it purely depends upon the other person’s choice – There are many who have not married even after the spouse have died just after marriage few other will get married since death has separated them and its not the end of life. What happens in life is so complicated. I shared that clip for this purpose, sometime we can’t find the truth – Whether that person was really died or not, “Sham tried his best to convince her that Arun has died, Believing that Radikha decided to marry Sham”. Here neither Arun was married nor Sham was remarried, but they had all almost the promise and love that is required for a marriage. It is legally wrong and morally wrong to marry if any of the one is alive and before getting the divorce.
