From my experience of grief it never goes away and never gets less. All you can do is add stuff around it so that it gets surrounded.
Grieving someone you love is very hard. All you have is memories and then you realise you can’t make any more with them. Everything you love about them is stopped and you will never see them again. And then your mind goes into remembering them and how things were and how you want that to be again but it isn’t going to be. That’s when the tears flow and with grief there is a sense of love and utter sadness.
