Here is my 2 cents worth, and I have seen quite a few friends pass away over the years.
No you should not feel guilty about moving on with your life. They would not want you to feel guilty about getting over them, at least that's they way I look at it.
I don't morn my friends, I celebrate their memory and how they touched my life. I remember them fondly and they will always be with me wherever I go till the end of my days. Yes there will be sadness and there is nothing that can be done about it and shouldn't.
In my honest opinion, you should be celebrating Denver's life and how it affected you, and not his loss. Remember the good times and remember him always. That's the best advice I can give.
