That is too bad about the ending of their marriage. This sort of situation can be uncomfortable for many.

With her invite, make some snacky foods and lemonade or something. Food is ALWAYS a great distraction during those "moments of akwardnes". As others said, just listen. Be positive in conversation and just keep the chat simple or whatever.

If your energy is happy and positive surely it will be felt by your friend. Maybe give her a greeting card to let her know you will be there if she ever needs an ear.
