Good for you for your healing process and reamining strong with the NC! Its those moments you describe that I am still seeking very much
I had to smile reading your story. I do find it very, shall I say ironic. A witch burned... . but you hopefully burned much of the darkness she brought to you as well with the photo.
Mine was devout LDS when I met her (or should say was becoming devout) I was given a nuanced choice and ended up joining basically thinking I was doing something good. Long story short, recently, cleaning up a bunch of 'reminders' I burned a lot of the church propaganda. That too was a good feeling to be free from both it, and her.
I never thought about the pictures
