Do you know anyone who is divorced? My friend recently got divorced.
Actually I don't know anyone personally who's divorced. I'm sorry about your friend. Was the divorce amicable? 
I believe it was, as far as any divorce can be amicable. They didn't spend money on lawyers but were able to come to an agreement on the split of assets and child custody.
How old are the children? Old enough to weigh in on which parent to live with?
No I don't believe the children were consulted. They are younger and were not involved as far as I know.
Are the parents Catholic? In that case I presume they also got an annulment.
I believe they are Catholic so they probably did get an annulment. That will let them remain a part of the Catholic church after divorce.
Did they seek any marriage counseling for the underlying reason for their desire to divorce?
