I'm aware that this is a bit of an odd question to ask, but I was wondering if you could describe what it is that you get out of relationships?

Not just romantic relationships, but also friendships and family. How would you describe your desire to seek out others, or why do you feel close to them? In what ways does it affect you when good or bad things happen to the people you know, and why, since it's not happening to you?

I've been friendless and mostly isolated for more years of my life than not, and I have never been in any romantic situation (never mind a full relationship). I know this should bother me, yet it doesn't. However it does make me curious about what motivates other people to seek out relationships with others.
