 I came across this concept a while back that basically says that within a romantic relationship, the relationship itself is a third entity. So when you look at it that way, it's easy to see where an imbalance could occur. One, one or both people completely lose their own identity and lose themselves within the relationship, making that relationship the only entity. Two, one person completely loses himself within the relationship so their own identity is gone and solely based on that relationship and the other person because then there becomes two entities, the relationship and the other person. Or three, the ideal scenario. All three entities remain imbalanced and intact and therefore imbalanced into harmony. Each partner takes care of themselves, keeps their own identity and interests and likes while contributing wholeheartedly to the relationship entity. So which one do you tend to fall under?
