Everyone goes through a grieving process for things at a different pace. A good friend of mine lost her fiance to liver disease when he was 26. This was four years ago. Six months after people were hounding her to "move on", find someone and she just wasn't ready. I'm happy to say she met someone in her own time and they were married last month. She's still not "over" G.'s death but she is moving on with her life and is happy.
I've never had my home destroyed and had to start my entire life over so I'm not going to tell someone when they need to move on or get over something.
