A relationship is only a good relationship if the other person cares about your best interests and wants you to have your wants and need met. But this does not mean that if a person loves you, they should sacrifice their own best interests, wants and needs for yours. What it means is that both of you need to master the concept and practice of communication, as well as each of you caring for the other's wants and needs; so as to find the highest and best win-win scenario in any situation.
