Look sweetie, you can't let things like that push your buttons. She's already told you she wants a D, so don't be surprised when you see her to things that endorse it.
Do yourself a favor and stay off her FB page b/c whatever you see is going to make you crazy.
I guess I've convinced myself that this entire time she is under a great deal of inner turmoil over her decision, where part of her is saying divorce, while the other part is questioning it. I may be naive for thinking that the part that has greater say is the latter, because that is the part of my wife I know - the caring, empathetic and loving person.
