"Moving On..."

You don't "move on". Or move forward. You move with grief. I think of it as parallel processing. The grief lessens in intensity and domination of your waking moments, although it still ebbs and flows to higher levels during random moments, holidays, and important days. But it is a constant companion. The memory of your loved one is, as another loved one described to me, "etched into your heart", and the grief associated with loss never goes away and you don't move on. If you are fortunate, that grief informs you, changes you in good ways (makes you more loving, empathetic, open, non-judgmental, etc.), helps you learn to sit with your feelings and just experience aliveness in all its forms.
