I feel so sad and sorry for you, I'm 2 yrs into being a widow so I feel your aching heart !
I sometimes feel like half of me went with him. I found the best thing for myself was to cry each time I felt he tears
coming, helps to relieve some the grief for a little while.
Hope you are starting to see a brighter future. Things take time and some issues/memories will be there forever. Stay busy clean up the estate and his stuff as soon as possible. Leaving the personal stuff go too long will make it harder to deal with later. Yes somethings you want to set aside get appraised or give to a specific person but get rid of asap.
