This freaks me out

I am so freaked out. My son went to see his biological father last Saturday and he comes home and he had me some pictures that his dad wanted me to have and Il looked at them and they were some of our wedding pictures. I asked Michael what the deal was because the pictures kind of freaked me out. Mike proceeded to tell me hhe kept all of our wedding pictures. I could see that if we split on friendly terms. When the last thing he told me was he was glad that I wasn't a part of his life anymore and he would like to see me dead. Why does he have those pictures when I all but burned mine and what does his wife think about him having  them. And I wonder what his second wife thought. It is so creepy. I just don't knw and he scares me alot.
