Riddle this for me

[Parththakkar12]

A : 'I want a relationship so bad I can't see straight.'

B : 'You don't need a relationship for the following million reasons.'

Why are so many people eager to prove to each other that you don't need a relationship/relationships?

[Spiral]

Simple, if they are eager to tell you about it, they are probably lying to themselves.

[Parththakkar12]

Of course they're lying to themselves! I'm interested in what could those lies potentially be, and what is the truth?
