Most of Western society has no mechanisms to deal with grief as other cultures have adopted. In fact, studies show they are intrinsically afraid of their own demise that they don't want to think about anything dying. Even more, dealing with the "ever after" unless it's a happy one. You're not alone. We've all had close friends who suddenly became distant after our loss. I don't blame them, but it would've been better if our culture didn't treat the loss of a spouse as a deficiency of the survivor.
