By Webster’s Definition

First I will define by Webster Dictionary some of the topics I shall be talking about here:
Relationship is a specific instance or type of kinship, a romantic or passionate attachment, the state of being related or interrelated.
Love is a strong affection for another arising out of kinship or personal ties, affection based on admiration or common interests, warm attachment, enthusiasm, or devotion, the object of attachment, devotion, or admiration, to hold dear. Love is a deep, ineffable feeling of tenderly caring for another person.
*I know there are many more things that can define what a relationship and love is, it has many forms and there are different beliefs about it, they are both hard and confusing, I will talk about it more later and define it by my beliefs (from what I have gathered from articles and reading). And since people can mistake lust as love:
Lust is an inordinate craving for the flesh of another, intense or unbridled sexual desire, to have intense desire or need for something, an intense longing.
