Societies always see a decline when family as a core is no longer a priority. I think that the best way to love someone is to first take good care of yourself in order to be able to also help the other. A relationship where only one person wants to advance while using the other will never last. Grow together or indeed fall apart is the rule. Once personal progress is near zero of course that there is nothing to offer in that relationship. Happy relationships are hard, but they surely deserve the work in order to build a beautiful family and long lasting principles for generations to come.
