Wells.....it is only natural that you would miss someone that you have been with for 10 years. And you are grieving at a level that wasn't possible while she was still in the house......I agree that you are where you need to be, at this stage.....
***helpful hint....it does help you to begin to make changes in the physical environment...as you feel that you are able to,,,,,
Even small changes......Like, but not limited to:
Paint a wall or a room a different color....
Move so me pieces of furniture around....like, maybe change the position of the bed...and get a different quilt or comforter......
Change some of the art work on the walls....
Change some behavior patterns....like drinking morning coffee or tea in a different place.....
Goal---the more you change the environment----the less triggering you will experience......
I think you are doing fine.....
