Love isn't a feeling, it is an action and way of orienting oneself towards a person so that you are sacrificing yourself to be the best person you can be and to help that person become the best person they can be. In a romantic context it is orienting yourself towards that person in a special way where you make a lifelong commitment towards that person that you plan to have in your life for the rest of your life and is focused on becoming one in spirit together as you both help each other grow and dedicate your lives to this process of helping each other grow and sacrificing for one another while always loving and accepting each other for who the other one is whether with their faults or despite them.

Just being attracted to someone or having feelings for someone isn't enough to say that you love someone, love is an activity and a development of one's personality and how one lives one's life due to that love. Loving a romantic partner requires the act of commitment to that person and doing whatever you can do every single day to help that person grow with you. It requires knowing that person better than anyone else in the most intimate way, caring for that person more than you care for any other human being, responsibility towards that person in being the best person you can be, and respecting that person as a human being, for who they are, and as your significant other.
