“Move on” is perhaps the worst advice about grief, especially in terms of loss due to death. You don’t “move on,” you live differently, you adapt, you overcome, but “move on” implies that you don’t look back or take anything of that loved one (divorce, change of plans, or death) with you. You do, you can’t help it, so examine it and carry it with you in an appropriate way.
