Of course there is a certain desire to find a partner, and it can be taken as a "flippant and facile generalisation" that people shouldn't need a partner, but I think what HPF is saying is that relationships should not be based on reliance upon somebody else for happiness, rather, the "need" is different, it is the need to be loved, but it should not be something that consumes somebody in their entirety. I've been single my whole life, and used to despair in my loneliness, making ironic remarks about people being miserable about being "alone" for more than 3 months. But I realised, life is also about self-love and finding one's own journey, and along it love may be found, and will make me a happier person, but it shouldn't be the ONLY thing that makes me happy.
