Good companionship is often what sustains relationships long-term, as it reassures partners that they have someone to lean on, share responsibilities, and celebrate life's joys.

In essence, this quote captures the idea that a meaningful relationship is much more about enduring companionship than fleeting passion. It values the everyday reality of sharing a life, emphasizing that the simplest measure of a good partner is their presence that you can genuinely live with.
