What really can you do? You can make yourself available to her and be a warm wall she can lean on, but finding her way through the healing process is something she must do on her own.
In time, she will be ready to move on with her life and she probably needs to hear that...but just not yet. Just let her know that she is loved and she has your full support. When she feels like opening up a little more, you may gently remind her of her fine qualities and what makes her so special.
Best wishes to you and yours - C.J. Sledgehammer
