Hi HA
I dont use Facebook, but I know you can delete the comment if you want to and still keep he photo. If is hurts you too much, rather get the copy from your mom:)
The feelings you are feeling are normal, but remember that you are free now and that he is not part of your life anymore, he cannot hurt you anymore. So dont let his name make you fear him, he cannot do anything to you
Hope you feel better
