In this case, I think it can not be ascertained, because love can not be measured. When we love someone, we do not know how much love we give. We give everything that our loved ones can be happy. Neither woman nor man can expect her partner to love herself bigger than the love she gives.

I think love has no strings attached. If you have a pamrih it's not love. Loving someone sincerely, never expecting a reply. In a relationship, love must arise from both sides. Mutual respect and mutual understanding are things to note.
