My father died and my stepmom is throwing out all our family photos.
If you have a hard time coping, sometimes, it's easier to get rid of anything that might remind you of them. That's just how some people react. It's easier to move on than constantly worry about thinking about them, and having another episode every time you see their face.
No its not wrong. My husband died last Halloween. I gave/threw away almost all things that reminded me of him. I put away all pictures of him so I couldnt be reminded of him because it hurt too much. We were married 34 years. So If it feels better to have your photos put away or thrown away after your loved ones death, by all means, dont feel guilty about doing so, if it helps your healing process. Condolences on your loss.
It is wrong if she hasn't got your approval! If those photos mean something to you, stop her. She is going through something but throwing these away will not help. I know this because my friends father died and the children are keeping the photos as memories. They are chucking out his tools and all his stuff but keeping the memories.
