So sorry for your loss

When I read your post I thought that maybe you could start a scrapbook of sorts... With stories about him... Get lots of different people to write their memories, and/or you write the story of his life. Write about your memories, things he said, places he went, where he lived... All those things... And it can be a work in progress..... You never have to finish it cause each time a new story is recalled you can write it in... Perhaps even with then kids help... They could draw the pictures to help... Or something.

Look after yourself... There is lots going on for you right now... So take your time and do what you can when you can xoxox
