Letting go of Possessions

I don't feel ready to let his belongings leave me. I don't throw away anything he has written on, or any receipt from our last trip together. What I have been able to do, is to pass along some of his clothes to my friends or family. In this way, I am not giving them up entirely, and there is even a sense of comfort when I see someone wearing them. This is not to say I can let everything go yet. I still keep the clothes he was most at home in. They hang in my closet, and our dresser still holds his socks, tees etc. I can't seem to get rid of the projects he started when Time was free to him. He started so many useless and varied projects, but they still are all I have left of that part of him.
