Keeping his memory ALIVE is a great thing. But you just have to know how to do it healthy, positive ways. Its not been very long for you, so it will take time.. but doing tihngs like starting a scholarship in his name, volenteering, donating things in his name, and just really striving to be the best at whatever you are following in life-- will honor his life..
It took me a long time to learn , that the only way I could keep the girls memory alive, was to move forward with my life, and work hard in school and life. Because if im not here, and dont take care of myself, and die, there will be no one to remember their sweet faces and what we all went through that day.

Honor him in the way that would make him happy and in doing so will keep his memory alive. For me I love pictures and have a big photo album full of pictures of my husband. I will treasure them forever. My husband enjoyed two things: drinking beer and playing keno. I will honor him when I social with my friends. The other way I can honor my husband is by doing the things in our apartment that he talked about like getting a couch for the livingroom. These are ways I can honor my husband. You know your fiance and what would bring honor and good memories for you.

people stay 'alive' through the love, thoughts and memories of others. the fuirst task, however, is to get yourself the help you need to just be able to stand in one pace at a time
