They care about me and want to make it all right again. But they can't "fix it," and this presents a hopeless situation.
Our lifestyles are no longer the same. I am no longer part of a couple. I'm dealing with probate, interpreting insurance forms, and wrestling with finances. They cannot relate to where I am.
Some people are not comfortable handling their own feelings, much less my feelings.
Joe's death is a threat to their own mortality. If he died, so will they. This is too difficult to handle.
They want me to be finished with my grieving and I'm not. Their time limit for me has expired.
My very presence is a reminder of Joe's death. It is more comfortable if I am not where they can see me right now.
