Is marraige a mandatory for women to live in a society like that of India?

If women are happy being themselves maintaining their morale values and character simultaneously flourishing in their career prospects then is it necessary that she has to even consider marraige inorder to be a complete woman.??? Cant she live with out being married if she is happy having adopted orphan kids and caring them without being a slave to the tantrums of a hell husband?? ( forgive me and give me a sincere answer i might sound like a misogamist..cant help though)
