I have a friend from my chapel who is civilly divorced. A little over a year ago, her husband, who was raised traditional Catholic, deserted her and their child, and left the faith. A civil divorce soon followed. While she is understandably upset, she accepts that she is still married, and cannot remarry.
My question is, on a social level, how should she present herself? For example, when meeting new people, does she say that she is married? Does she refer to her husband as her "ex"? Does she still wear the wedding ring? Should she continue using his last name, or revert to her maiden name?
I doubt the Church has any explicit teachings about this, as it is more social question, but any guidance you can give is appreciated.
