Coming to terms with a death is a very gradual process which can take a considerable length of time. People usually find that they are able to get on with their lives and think a little less about the person they have lost. Most people begin to feel like this within one of two years of the death of a loved one. It may be difficult to accept the death of a loved one but possible to move on with life in spite of this.
It is important not to feel guilty if you are beginning to build a life for yourself following a death.
