AC, I agree with the others. Don't give the friend's comments too much thought. It is too hard to say what was behind what your W's friend said to it. Bottom line is she is not your W anyway.
I think Brit's advice was excellent: keep your interactions happy and fun with your W and build good memories. Have no expectations.
Ultimately, if your W wants to come back, she will make it as clear as the day of the bomb she wishes to do that. Meanwhile, make your life excellent and your W can choose to join you or not to join you.
