Getting in touch with the Love of my Life..

On Dec 6th, 2014 I lost my best friend, partner and the Love of my Life. An exceptional soul.. I still don't know what happened, don't understand it and cannot accept it. I am looking for signs, and for him, every day and night. I am a skeptic, but I am doing my very best to believe, and stay open. Could you please help me get in touch with him?... His name was Mark.
