When you get divorced, how do you decide who gets the friends?

It seems to me that if you have mutual friends, and you both try to remain friends with your mutual friends, then you are likely to see each other, and that could be very painful, especially if you want your ex back.

I imagine you might end up in a position where one or both of you call the mutual friends to see if your ex will be there. Perhaps the division depends on how acrimonious the divorce was. Perhaps it hurts one person more, so they voluntarily take themselves out of the picture. Or maybe one person is more depressed and they just retire to their cave to die.

Have you ever been in this position, either as a friend or as the divorced person? What happened? Did it happen by plan or by accident? Who went with whom? Why did it happen that way?
