Yes, indeed, I want to totally second what Greentea said, because it's a very accurate observation.
A lot of my friends acquaintances have even - what they call - best friends hat they, despite this termini, do not trust completely, may find annoying and they complain about behind these people's backs. They stick together with them, freely choose to spent their time with the same people they complain about to another and they feel connected with those people, feeling different degrees of concern.
It makes sense to have a social life like that (if balanced), because not all social relationships are for true love and sympathy. Instead social relationships are useful for such things as connections to important people, being able to spend time with different people according to different situations (big one), being able to chat about everyday things, specific topics according to that person's interest etc... endless possibilities, I doubt I even know all.
My point is, relationships are a tool and are not (primarily) designed for finding a person to share everything with/the purpose of relationships is not having only emotionally laden relationships.
Oversimplified, relationships mean that different areas of life are being shared with many different people in many (sometimes opposing) ways.
