SS, I have the same sort of feelings. Anger almost hatred in waves, I think this is a normal part of grieving. I don't know which way I will land, angry at her or not. I'm praying alot and seeking counsel from my pastor, IC and here. I completely understand where you are as I am there, I'm just trying to ride the wave before I say or do something I'll regret later.
I'm wishing you a calm productive day.
You can not change your past, but you can ruin a perfectly good present by worrying about the future.
