<human>: Give me a shortened version of the text

Hi! I've never posted here, but yesterday my mom told me something that left me very unsettled and I really don't know how to feel.

So I've always thought I've known my mom's past relationships. For the past 17 years of my life she has told me about the few people she dated in high school and college until she finally met my dad at age 32 and married him and then had me at age 37. That's it. That was the story.

My mom is a schoolteacher and a simple christian woman. she tells the truth and lives an average middle class life.Which is why yesterday I was so shocked when at a dinner out together she told me that she had something to tell me.

After college she married a different man we will call Phil. They were married for two years when one day she found psychopathic diaries and pills in his drawer and confronted him. He turned violent and she broke off the marriage. She saw Phil a year after their divorce at a festival and  she saw him with another woman. she was glad he moved on, but felt bad for the new girlfriend.
BUT IT DOESN'T END THERE
A few years after their divorce she gets a call from her brother and he says "turn on the news right now" . On the evening news was a picture of Phil and that woman from the festival with the caption "couple found dead in hotel" . Turns out Phil murdered her, and then killed himself. 

I sat there in absolute shock as my seemingly normal mother told me a story that could be on a lifetime movie. What's been bothering me is that apparently her whole family and my dads whole family all knew this. Her coworkers know this. My best friends parents moms this story. I was the last to find out because "she didnt know the right time". My whole view of my mother has been altered and I don't really know how or what is normal to feel right now , especially since I'm the last to find out.(besides my poor brother who is in college and my mom STILL hasn't told him) 
Sorry this is super long but I'm just unsettled. Any advice is greatly appreciated.
<bot>: My mom just told me she has been previously married to a psychopath and I am unsure about how to feel. Any advice on how to move forward?
