It is easy to be a good person when everything is good. Being with a person in hard times can show a true character. How does he behave when he is tired or sick, when there is distance between you, lack of finance?
Ask questions. For example: What makes it easy for you to be open and vulnerable, and what makes it difficult? How would you describe who you are to another person? What do you believe are five elements that make marriages work?
Love is not blind, capricious or irrational. It is not passionately ever changing emotional moods. Love is constant. It is your moral attitude, it is your determination to wish and do well to your partner even if he or she does not deserve it or does not respond mutually or acts indifferent. Once you are with a person be ready to give more, sacrifice and serve.
