Let him get on without you. The sooner you make new traditions and 'norms' the sooner the pain will go away when you are reminded of things you used to do together. I remember it was terrible when I had all the firsts that were without H because I was always flooded with how we used to do this or we did that blah blah. Once my new norm started to set in things were a little better. I know it's hard! Just trust in the process ... Let him go and leave him be. Make Memories and life plans without him. He's already gone anyway.
