As everyone has said this is a long mourning process. It is normal and healthy to cycle through periods of sadness and missing your w and the life we shared. I think the way the WAS seems to not care about the end of a marriage is not healthy and will have to back up on them at some point some day.
My father passed away over 10 years ago and I still have moments of unexpected sadness.
While on vacation last week I had 3 incidents of missing h. At one point I was very tempted to call him but talked to a friend instead about what I was feeling. She didn't understand how I could miss someone who treated me so badly but seemed to understand when I explained I missed who he used to be.
Keep feeling and processing and living. You are doing really well.
