The hell he does. Yet Prachi screamed that although she worships him he did not seem to need her. Hope the girl seriously does not believe that and her accusation was just the heat of the moment thing, just as Milsi's yelling at the beach that he'd rather stay childless than have a child through her.
Milsi very clearly told her at the beach that he did not know the meaning of life before but now he cannot live without her. The guy depends on her for his life. If this is not need, what is? She was the one who brought a calm and peace to his tormented soul. When he was with her (in body and spirit) he realised the softness and tenderness he possessed. She was the one who could quieten down his emotional turmoil. She brought out the best in him. Ironically she is also the one who can bring in the exact opposite effect when he feels threatened of losing her. He then becomes a bundle of untamed emotions and the worst in him manifests itself on her.
Milsi wants her, yearns for her and, most of all, needs her more than even he himself realises. So Prachi better believe her own worth to him and stop putting herself after everyone else. By doing so she is putting him at the end which is not what she wants, as she herself said she worships him.
