You love not because you need someone.
Not because the other might some day prove useful. You love because love is awesome.
Because in the company of the right person there is no telling what you can become.
Relationships are for walking with someone along sometimes rocky, sometimes rainbow lit roads. Being in one does not compromise your freedom.
Relationships are specially designed to teach you how to hold something precious with open palms rather than trying to hold it captive.
Beyond a partner, all these things hold true of any relationship.
