Whoever says single parents are not allowed to find another mate is dead wrong. Single parents still have the right to be happy even if society dictates for them to just take care of the children. I recalled my
Asian History class. Widowed Indian women are required to commit sutti the moment their husbands die. They are not allowed to enter another marriage even if they wanted to. But this is not feudal India, it's the postmodern era now. So dating single parents is perfectly normal and acceptable in most societies.
