Still bad, after 5 years

It has been 5 years, and it has been a blur when D- Day on 2.1.2013, crushed on me. I do not think I have made any progress, and the Christmas holiday and new year for the past few years are very difficult.
Never a day goes by I am not thinking about it. I am still stuck at how could he, after being married for 33 years. He just expects me to snap out of it, after he has said, I am sorry.
I wish I could make it easier for myself. It is me who is trying hard to recover as he said it is all in the past, and why am I still living it.
