Is there any discussion about true nature of relationships in Buddhism?

We are social animals and while living in a society we make relationships with other humans. Relationships like mother,father,son,aunt,etc. are determined by default ie, we don't have choice. While some relationship have to be chosen by us eg wife, friends, religious master, political leader etc. While doing so I feel majority relationships are more like **treatise** or **agreements** they thrive on mutual interests and break once they are not met. Some relationships are temporary which exists till both parties are involved in particular task and get over once the task is completed like relationship of boss and employee. Some relations are considered pure since they are said to be driven by emotions rather than any purpose like that of parents and their children, but I am doubtful that there is mutual interest hidden deep under them, which maybe realised if we end our attachment. I find understanding nature of our relationships is very crucial to avoid suffering arising due to ignorance of truth behind them. Is there any discussion on this issue in Buddhism?
